Hi - it’s nice to see an active & supportive community here. I just wanted some input about my situation. I know it’s probably unlikely but want some reassurance from other people. Thanks in advance!
To begin, my cycles are usually less than 28 days. I would say I average around 24-26 day cycles and my periods last 5-6 days. So I started a period on August 20th 2022, however I had unprotected sex with Guy A during menstruation August 20th-22nd. He did finish inside of me on the 20th and the other two days were pull out method. I never have sex with this guy again after these encounters.
I had sex with Guy B on August 29th, who also finished inside of me. When I checked my period app, this was suggested to one of my high fertility days so I took a plan B. But from this point on, I am only having sex with this guy.
I started my period on September 12th but anxiety has me thinking back wondering if I can completely trust this was my true period. I know I used tampons for this, but I can’t help but think back like “omg was my flow the same, did it last as long as usual” etc. Anyway, I cannot list all the days we had sex in Sept, but I know we had sex on Sept 25th with him finishing in me. Any other time in Sept would’ve been pull out method. On my period app, the 25th was the first day outside of my “high fertility window” meaning the calendar was showing my high fertility days were the 19th-24th. I know these apps are not accurate for tracking ovulation but just giving as much info as possible. I also assume August’s Plan B could’ve also affected me for the month of Sept and shifted my dates. So fast forward to October, I miss my period. I don’t remember what day(s) my period was supposed come but on Oct 4th I took a pregnancy test (not using first mornings urine) around 4pm and it was negative. I ended up testing again with first morning urine on Oct 8th and got a positive result.
On Oct 9th, I went to get an abdominal ultrasound at a boutique and all she could see was a “swollen uterus”. I went back on Oct 19th and the sac at least was present. I have anxiety over the Oct 9th scan, because one time my OBGYN told me via Pap smear/pelvic exam that my uterus was slightly tilted towards my back, so it makes me wonder if the abdominal ultrasound would pick up anything that early. When I went to my first official doc appointment to have a transvaginal ultrasound on Nov 9th, my LMP dated me at 8wks2days and the AUA they measured was 8wks5days. At my 12 week appointment on Dec 5th, I was also measuring ahead can’t remember the numbers exactly but no more than week at that time. LMP dating was 12wks. Anyway, my due date is June 19th according to LMP and they have not made any changes to it, but as you see my AUA never quite matches up to that date but I assume this is because I don’t have 28 day cycles? As I get further along in my pregnancy I understand ultrasound measurements are no longer accurate as at my anatomy scan at 21wk4days, baby was around 15oz and seemed to be measuring a week ahead. I just don’t want to get to a point if the baby measures like 2-3+ weeks ahead and makes me go crazy even further.
With everything I’ve shared, can I really trust that I conceived sometime mid-late Sept and rule out Guy A being the father? Like no chance at all? Even if somehow my due date changes later on in pregnancy to early June? (See how my mind works?) I really want Guy B to be the father. I think I would’ve felt better if I had two periods in between the encounters, but the one period and google searches just has me wondering if it’s possible. Logic tells me I’m okay and I don’t need to spend $1k+ on a prenatal paternity test but my brain and the GUILT just has me going left at at times. I really want to put this to rest & enjoy the rest of my pregnancy freely. Feel free to add all the reasons why I’m most likely being unreasonable here. Thank you sooo much for reading this long winded story.
