Just putting out here because I'm worried, but I also feel incredibly stupid for putting myself in this position and not thinking twice.
Not too long before pregnancy I used to run quite frequently and at a relatively fast pace. I took up running for about a year and I would run 4 to 5 times a week between 5k and 10k sometimes throwing 1/2 or a marathon in. Everytime I ran my average HR would be around 185bpm throughout the entire 30mins-1hr which is considered very high (I'm 32 and my max supposed to be 188 which is basically a sprint pace and can only be sustained for a very short time). Aside from overheating quickly and thus only ever running in t-shirts regardless the snowy weather I felt fine and always wrote it off as my bpm range being outwith what is considered normal. My rest HR was about 43bpm wich is also considered low. I have never done any medical tests with regards my HR.
Around September 2021 I had an injury and stopped running. Then in February this year got pregnant. I had an awful first trimester majority of which I was bedridden anytime I wasn't at work. This only has improved about a week or two ago, I am currently 18+5. I never had any stomach aches or spotting at all, I mostly struggled with digestive issues and nausea.
I felt very guilty having done 0 exercise and having gained a little over the recommend amount throughout the past few months and so I decided to do something active. I googled and it did say if you ran regurarly you would be okay running while pregnant provided you dont push yourself too much.
Being midful of not having had any exercise for a period of time I thought a light jog would be appropriate and not too hard. I set of on my usual 5k. I went VERY slow, I could've speed walked at the same pace but wanted to keep the bounce of a jog as it's something I find easy to zone out to. I felt fine for the most part, muscles were out of practice and I did feel a bit warm but with a sunny day I just kept to the shady parts of the path.
When at home I felt fine, drank loads of water and had no issues in general. I checked my run's stats and saw that the entire 34 minutes were spent between 185-190bpm which is just mind blowing considered I felt so fine. Then before bed I noticed a couple of broken capillaries and kinda freaked out a little. I had no other pains other than headache so went to bed as usual having cried to DH about being worried.
About 2am I woke up with stomach pains throught the entire abdomen and bad headache. The pain wasn't severe but enough to wake me up and keep me awake. I started to panic. It went on for maybe 2 hours at which point I took painkillers and decided to call the duty midwife.
The pain has passed after the painkillers but I was too wired up to sleep. Midwife advised to call back if the pain returns but otherwise not to worry and to not jog again, saying that I just overdid it. I have my next scan on Wednesday morning but feel like until then I will just drive myself mad thinking the worst, although the stomach pain has never returned.
I now feel I should've gone to GP first time by HR was that high before I ever got pregnant but at the time I felt more than healthy and I loved running, and hate myself for not checking HR during the jog.
I'm so confused and worried by this.
