Hm looking at dates idk the exact day of last period I just know I only had sex one time august 30th before I got pregnant my period was around the 15th doc said yesterday I'm 8 weeks 2 days by ultrasound so according to the dates I probably would have been ovulating like that day I think since the boys swim faster. Still hopeful for girl though .
