Severe "night chills" - anyone else?

Ok, this is a wierd one...

Have NEVER had it before, but have now had it twice in second tri (last night and almost 4 weeks ago exactly) - both followed very similar pattern:
- was asleep in bed.
- woke up middle of the night, felt a little cool, but not ridicilously cold, needed the toilet.
- got out of bed and went to the bathroom.
- before I got to the bathroom, I started shivering, the shivering became more and more violent and I felt EXTREMELY cold (no other symptoms - no dizziness, no "jelly legs" nothing...).
- went to the loo, run back into bed with uncontrollable shivering, then proceed to use husband's whole body to heat my whole body.
- feel absolutely "cold to the core" (brain feels cold, heart feels cold, everything feels cold). Husband says that I don't feel hot (doesn't feel like I have a fever or anything). I just feel like I cannot warm my own body (like my blood wont carry any warmth) or get warm (touching his body gives me a warm, tinglely, slightly burning sensation).
- still shaking/shivering for a good 30/60+ minutes.
- within 2 hours, back to normal (went to the loo again 2 hours later, was fine ).

Baby is fine - was kicking up a storm afterwards (am not suprised...). Took temperature this morning (when I got up) - 98.6...

When I first had it (4 weeks ago), I dismissed it as a freak event: maybe developing a cold or something that I fought off rapidly in one nasty go... The fact that it happened again, last night, seems to suggest differently...

I don't think it was PARTICULARLY cold last night (it certainly wasn't 4 weeks ago - it was a fairly warm night) and I have been a in a LOT colder! We regularly ski in USA/Canada and I have quite a lot of experience below -30'C....

I did various goggle searches and it doesn't seem to be a recognised symptom of pregnancy or low blood pressure (my pregnancy blood pressure is about 90/60, was wondering if that could be a cause...) or taking baby aspirin (which I have been perscribed).

I would really like to prevent this happening - as Winter progresses, would seem likely that it could happen a LOT more . And also look for ways to try to stop it as soon as possible - if husband wasn't there, goodness only knows what I would do (probably run on the spot or take a warm shower ).

I have an emergency GP appointment this morning (hands still a little numbish, head feels a little funny too). I am seeing my Obstetrician on Monday (for the first time) and this will be on the list to talk through with her. But, in the mean time, was wondering if anyone here at any similar experiences?

thyroid perhaps?

Might be worth asking for a Thyroid function Test at the GP's.

I have low blood pressure too. Have passed out twice because of it. I also go through periods where i am so incredibly cold that nothing seems to warm me up. The day before yesterday it was 27 degrees here in london and i am in tracksuit with my husbands big hoodie jacket on cause i could not get warm. My GP sent me for blood tests yesterday to check my thyroid. Getting the results in about 7 days.

I was incredibly cold and prone to violent shivering from the onset of my current pg in Feb until it actually started warming up this summer. I was carrying round the woolliest cardi I could find with me everywhere and just never seemed to warm up ever! Others have said that they have suffered similarly too.

I had it first trimester with my first. Absolutely bloody freezing all the time - any spare minute I got I was wrapped in a duvet. I put it down to my body working extra hard and diverting all available energy away from non-essential tasks (ie the task of keeping me warm).

I had this a few times in my last pg - I am a 'cold' person anyway - always whinging about being freezing but I had a couple of episodes just like this where I had sudden 'freezing attacks' in the middle of the night.

I spoke to my brother who is, handily, a Dr and he said it i probably related to blood pressure (mine is also always low) and blood sugar - baby taking blood sugar all the time might lead to a sudden inequality hence shivering etc. Other than that he said it could just be due to changes in circulation and sleeping more havily - eg not moving about and therfore just getting colder.

Thanks very much everyone - I was beginning to think that I was alone in this (I have serached google and had little luck in finding anything relating "night chills" - or severe shivering - to pregnancy). It obviously isn't a common symptom and is pretty darn frightening really... (at the time).

I saw the (emergency) GP yesterday and she seemed pretty mystified... her main thought is that it is a high temperature brought on by infection (most probably UTI). I am not HUGELY convinced because of it's sudden appearance and sudden disappearance (been, violent, gone within two hours...). BUT I have to pee into a pot (seems the standard answer to everything in pregnancy) and see what the lab says. No other tests ordered at this time.

She did take my temp (which I had already taken) and it was normal. She also took my BP and I am optimal/lowish (but not worrying low - something like 105/65 I think). Will see if the urine test picks up anything (I have no other symptoms of a UTI), if it doesn't then her answer is "wait until it happens again and they will run more tests" ). She has told me to keep a thermometer (to check my teperature if it happens again) and some paracetamol by the bed.

I see my Consultant Ostetrician (for the first time) on Monday and this will be on the list to discuss... maybe she can shed more light.

To be honest, I am not normally a "cold" person. I am not a particularly hot person. HOWEVER I do have circulation problems when skiing (just to my fingers and toes). I have boot heaters on my ski boots and - when temperatures drop below about -10'C - I do tend to pile on the glove liners and chemical hand warmer. The rest of me (my core, head and limbs) never gets cold ridiculously cold, though... So there MAY be something in that.

I am definitely moving LESS in bed than before pregnancy (even though I am only just about 20 weeks). I don't get on with body pillows (too restrictive), but still find that I am not moving as much as before (more effort to move and get confortable). So that seems like an idea...

To be honest I am now DREADING the Winter: it really ISN'T cold at the moment - surely this will only get worse as it gets colder.. sad. I can't see it NOT happening again...

I can see an expensive heating bill and an unhappy husband this Winter (not because of the bill but because he hates sleeping in warm rooms...).

I know this is an old thread, but for anyone else researching about this happening too, i thought I would add my experience.
I am 38 wks preg now.
This happens to me sometimes too, when waking in the night to go to the loo (no other time).
Infact, just last night it happened again.
It doesn't happen every night, or everytime I go to the loo, but sometimes, i get up, I'm on the way to the loo and suddenly feel cold and think if I just run and pee really quick, I can get back in bed before I get too cold but it comes on SO SUDDENLY that I am violently shaking cold.
It is a scary cold- as the OP said, to the core.
I curl back up in bed in a ball and shake and shake until I re-warm up.
Yet next time i get up in the night, I'm fine.
I am not unwell, no infection and it happens randomly.
I now keep a thick dressing gown right next to the bed, although i didn't use it last night as I felt fine until half way to the loo, then it was too late- it had already hit me.
I don't know what it is either?
It has happened before too where I wake up not covered up enough from a deep sleep and feel deathly cold.
Then again, last home birth after baby and placenta was born and I was dressed, sitting on the sofa, the midwife took my temp under tongue- then took it again, shook the thing and asked me to do it again looking quite concerned!
I said "Oh, is that showing a low temp? my temp is always lower than 37c" and she said yes, but not just low, its showing 34.3c!!!! (which is going into shock/ hypothermic kind of temps!)
I laughed and said I have seen that before, not always that low, but I have been that temp before when I have taken it myself, and been fine...I was feeling fine after the birth too so she took me at my word.
All a bit odd really!
But yes, other pregnant women out there have experienced similar OP (never when I'm not preg either!)

I know this is old and i hope you lady's can tell me how the rest of your pregnancys went? So last night i was in a deep sleep and felt i had to pee it felt a little cool under the covers so i got up real fast ran to the bathroom before i even got there i got this sudden feeling of being cold i started to shake uncontrollably it hurt so bad i couldn't even finish peeing. I got back into bed and was still so cold i felt terrible and scared like i would never warm up. I had it happen once before but not as intense i had a migraine i couldn't get over that whole day. And now its worse im really worried there is something wrong. I'm glad to see other women experienced it but nobody has updated there pregnancys and it has me worried. I don't want thus to happen again also i am only 12 weeks.

Trisha88 Sun 03-Dec-17 14:14:41

I have read your thread and it was like you were saying what happened to me exactly. Can you tell me if it happened anymore during your pregnancy and how the rest of your pregnancy went

I had this really randomly at 14 weeks and it was scary at the time. Midwife had no explanation for it but my gut instinct was that it was something to do with my blood pressure. I had woken up on my back, but wouldn't have thought that would have been significant that early. I'm 20 weeks now and hasn't happened again as of yet, but notice that when I do get cold I'm much shakier than I was before pregnancy!

CL1982 Sun 03-Dec-17 17:06:13

Yes I had this once or wasn't nice. I think it stopped about 22 weeks. Maybe check with your midwife or doctor?

Trisha88 Sun 03-Dec-17 18:16:53

Thank you I will this week

JenHJM Sun 18-Mar-18 11:22:16

I am 22 weeks and just experienced chills like you describe when going to toilet last night. I did have a busy day so not sure if it was being over worked. Otherwise feel fine yday and today but really freaked me out. Later wrapped in blanket to warm up and then woke with wet chest but body temp fine. Did you experience this too and how is your pregnancy or baby now. Next on appointment is in a week so need to wait til then unless it happens again

Rdc88 Thu 02-Aug-18 05:29:40

So I had this exact same thing happen with my last pregnancy during my 2nd and 3rd trimesters, totally random, at night, maybe 5 to 8 times. My thyroid was fine, my bp was fine, I always slept on my side. I don't recall if I ever mentioned it to my doc. I don't know if this is related (don't think so) but she developed a low fever around 12 hrs old and was put on antibiotics right away for her first week just in case by NICU. They ran bloodtests and even a spinal tap, they couldn't figure out the reason for the fever. She is now a healthy and full of personality 22 month old going into the terrible twos.

Anyway I am now 13 weeks with my 2nd and it's just happened again for the 1st time this time around. During my last pregnancy I developed pre-eclampsia around 40 weeks plus 5 days (I was induced at 40 plus 6) and developed hyper thyroidism and Graves disease around 5 months post partum (which against the doc's quoted odds, went into remission within 6 months of low dosage treatment). So this time, I will be mentioning it to my doc at my next appt and would love to hear back on what others were told by their docs regarding this weird uncontrollable shivering.
