My bbt temps after O are bonkers - anyone else had this?!

[matchstickpopper]

Hello, this is my first month ttc and temping (not been on hormonal contraceptives for years so no issues there) and my temps were on the low side before O (no thyroid issue, had it checked out). I O'd a bit late (on day 18) and then had 3 high temperatures around the same (36.2 to about 36.5), but this morning my temp shot up madly - it was 37.49! See my chart:

Didn't have disturbed sleep last night, house wasn't hot, didn't drink any alcohol the night before so no obvious explanation as to why temp was this high.

I guess I'll just have to wait and see what the next couple of days bring, I just wanted to see if anyone else had had this experience.

Also had loads of creamy CM yesterday followed by large blob of EW this morning (sorry for TMI). I thought perhaps it was possible that I ovulated later than I thought but I am pretty certain I O'd on day 18 as CM pattern and OPK backed this up....

Thanks :)

no one??

I've never seen a jump of a full degree like that, the only time I had a couple of crazy temps mid-cycle I was ill with some sort of food poisoning. O temps are usually only .4 - .6 for me, so I'd wait and see what happens. Maybe check your thermometer works properly or you didn't misread it? Sorry, don't mean to sound patronising, but I know it can happen early in the morning in the dark!!

Hi Matchstick - did you take your temp earlier/later than normal? You have indicated a clear dot (open circle) on your chart which indicates that something is a little different about the temp.

At this stage it's probably just a rogue temperature. It could be an increase in progesterone or just a wonky temp. At 4dpo it's too early for it to be a 'sign' of any kind (depsite how much we want it to be :))

I am sure someone more knoweldagble will be along in a bit!!

thanks for answers both, don't worry not patronising at all - i actually turned on the light to make sure that was what it said and made DH take his temp too to make sure it was working properly. and yes I take it at 6.30 every morning without fail.

guess i will have to wait and see what the next few days bring! there is no chance it is a pregnancy symptom as I am only 4dpo.

am now wondering if i ovulated later than I thought as I got EWCM today...but thought my temps showed a clear rise.

Just keep DTD to make sure and fx!!!

temps back to normal this morning so suspect it was just a random mad one....I now think perhaps I didn't let the BBT thermometer go down to 'lo' before I stuck it in my mouth
