I’ve really been just trying to figure out when i made this baby boy. Like i really wanna know my ovulation day. So if your good at this can you answer this. Okay AF started July 16,2018 stays on 5 or 6 days i have a 26 days cycle. I had sex July 15 day before my period. Regular period heavy as usual. Also had sex July 27-August 2. I really think i ovulated July 28 or 29 but I’m not sure. I’m only asking because i told my doctor at my first appointment my period was July 15 and have a 28 day cycle but i was wrong. I just need to know so i can make sure that i really am 24 weeks and 5 days.. every time i use a calculator online it says it’s right and that i conceived July 28-July 29
