Just looking for some advice and a handhold please.
I am previous sufferer of anxiety and some ocd traits which I was on setraline for but I stopped taking as soon as I found out I was pregnant. I’m currently 34 weeks pregnant and up until the 12 week scan I was blissfully happy that myself and my partner had conceived, even though we hadn’t been actively trying (I used the basal thermometer as a loose contraception but that month it had me down as ovulating on day 11 rather than 14 so said they were a few green days when it wasn’t meant to be) Anyway, at the 12 week scan they put me forward 5 days from this date and gave me a new due date- even though I said I knew the day I ovulated.
This then threw me into a complete spiral about how the dates could be so different and then the thoughts started: that the baby is not his and that I must have been with someone else on my birthday night out the weekend they now said I had conceived when I was drunk and I just don’t remember. I should add I remember most parts of this night, we only went to one place and we're home by 11:30- my best friend drove us home and stayed at mine the night, so unless I had sex with someone in the toilet that was a complete stranger and had never seen before that was the the only time it could have happened. I am really not that type of person and have never had a one night stand. I love my partner so much - so I sort of then just brushed it off as a silly intrusive thought, thinking I’d remember if that was the case .
However as my pregnancy has gone on and on this irrational fear is just getting worse, and now it’s taken over my life- so much so every day it will say to me ‘but what if it is true and you just don’t remember?’ 'Are you sure there isn't half an hour of the night you can't remember?' My brain is convinced the baby will be born a different race and I’ve not been able to enjoy my pregnancy- at every single single scan I analyse her face on the 2D scanner and think she has ethnic features such as big lips and looks nothing like my partner, I look at her femur measurements which are showing big and think because me and my partner are short it can’t be his as she looks like she will have long legs.
I’m convinced she will be born and it will break my partners heart and everyone will think I'm a liar and the worst person ever- I’ll be left as a single parent and I’m really struggling to cope now because I'm dreading the birth.
Does anyone please have any advice?
