I understand the position I've put myself in, and I can 100% swear that I will never touch alcohol again. I'm looking for advice here; please, please be kind.
I have irregular periods (one/two a year- very sporadic). I am married and pregnant, and my due date from my 8-week ultrasound is the 27th of November, 2023. I cannot calculate when I ovulated etc., because of the sporadic periods.
I went out on the 9th of March and experienced a blackout when drinking. For around 1 hour, I cannot remember a thing. My memory returned when I must have been chatting with a man outside the bar; my memory returned when I remember pushing him away from me when he tried to kiss me, telling him that I was married and running back inside, panicking, looking for my friend to leave. I remember feeling awful that I had got myself in a position for someone to try and kiss me. I felt awful and guilt-ridden for this; however, I do not remember at the time feeling guilty for something greater than this (i.e having sex with him).
However, I've now convinced myself that something further happened with this person, and he is the father to my unborn child, even though I have zero memory or recollection of something happening. Surely you would remember, even vaguely, having sex with someone in a public toilet etc. I was at a public bar, and checked google maps etc. to see if there is anything that would jog my memory - i.e. going down a side lane etc. I've experienced significant hanxiety before, making up situations in my head that didn't happen etc. I would never consciously cheat. From what I remember of the night, there was nothing 'obvious' to indicate that I had sex. I left straight away after this and went home.
The next day, I was guilt-ridden for getting myself into such a stupid position (him trying to kiss me. and me blacking out) but didn't even remotely think I had sex until I found out my due date. This is when this horrible niggling thought came into my head.
I've completed numerous online conception calculators that all say I probably conceived around the 6th of March, with my fertile window between the 28th Feb-6th March.
I have had sex with my husband before and after this date (I don't know exactly which days we weren't tracking). I've spoken with my therapist about this, who has said I'm most likely having this thought due to previous sexual abuse when drinking and not feeling in control). This was the first time I have drunk in over a year, and I can 100% swear it will be the last.
This is completely ruining the start of pregnancy for me. I remember the man being of an ethnic background, my partner and I are white, and I'm freaking out thinking I would have a glaringly obvious mixed-race child when the birth happens.
Going by the due date of the 27th Nov- when is it most probable that I ovulated/conceived?
Any help is appreciated. :(
