I'm being induced at 37 weeks for medical reasons. My cycles are 24 days long religiously. Based on this my EDD was May 13th but at my 7 weeks ultrasound it was May 16 which would be for a 28 day cycle. At 20 weeks my date went back to May 13th. I just want to know for the ladies with the due date of May 13-16 or the LMP of August 10th what was your conception date? I want to make sure he's actually cooked for 37 weeks. I got a positive test September 2nd AF was due the 3rd. I also had sex the 28th so I wanted to make sure it wasn't from that day because I would less pregnant, I think.. idk
