Hi ladies, hope you're all doing great and Congrats to you all..
I'm 26 weeks on Tuesday, baby girl due on the 1st of May.. Now I'm so confused as to when baby was conceived, bf and I were on and off at the time and I had unprotected sex around the 10th of July. LMP was meant to be on the 20th of July but I don't remember getting one as I was under a lot of stress after loosing my job. Had an ultrasound on 5th of Sept and it showed I was 5 weeks and 6 days.. Was with my partner after the 29th of July. Went to see Dr about it but he didn't really help..
If you ladies could help put my mind at ease as its something I can't stop thinking about.. Really need to know :/.. Please no negative comments, would like some help that's all.. Thank you in advance..

I'm due May 1st and my day 1 of my LMP was July 27 which puts conception sometime around the middle of August.  Hope that helps.

If you were near 6 weeks on September 5, the chances you conceived in the first half of July are pretty low since it would put you a full month ahead (i.e., April due date). Although our cycles can vary dramatically, most of the variation is in the follicular (pre-ovulation) phase while luteal phases (post-ovulation) tend to all be pretty close to 2 weeks. For that reason, it would be very unlikely that you ovulated before the beginning of August. Sperm can apparently survive up to 5 days but that still puts you at the beginning of August. Good luck!

That's really hard to say. It depends on how long your cycles are and when you ovulated. I am due May 1 as well and I have an app on my phone that says the conception date was Aug 9. That's probably not accurate though. You can concieve up to 3 days before and after having sex. Sperm typically live about 48-72 hours in the uterus. If you have a normal 28 day cycle you become fertile around the 10th day of your cycle. Do you remember when you had sex w/ your bf during that time?
