Bare with me it's sorta long. But I almost knew for a fact I ovulated January 26th of this year I used a opk got 2 dark lines which meant positive and everything. But all this changed when I got a new due date from my Obgyn , which was originally October 19th but they changed it to October 11th. I almost knew for certain when I had my period as well which was what I thought was January 12th. My new due date switched my period from that to January 5th. I thought about it, and that's actually my moms birthday. And I remember something happening that day, but I can't remember what it was maybe it WAS the first day of my period. I was in complete denial of my new due date untill I looked at my ultrasounds my ultrasounds actually matched up to the dates they were supposed to be of my new due date. BUT I also used a ovulation chart and I bled January 12th ! I charted that. So this can help me a lot with finding out who got me pregnant if I know when I ovulated. Can anyone make sense of my situation?
