My fiancee and I had sex Feb 20th and the 21st (when I was ovulating). I had what I think was my period from March 11th to 14th. I didn't receive any pregnancy symptoms so I thought we failed on ttc. I read from different websites you can and can't have your period, so i am kind of confused. I was suppose to start my period this month (April 10th) and I haven't received it. It's never late and I have been tracking my period for a year or so now and its usually dead on or a day late but never 4+ days late! Has anyone had this happen to them where they thought they had their period but turn out to be pregnant all along? I need answers.
