I have endometriosis, which means that I do have a slight chance of being infertile. However, I have not had my fertility tested. Because I have endometriosis, I take Ocella birth control pills to ease the abdominal pains. The first day of my last period was on June 30, 2009. I know that this means that on a regular 28 day cycle, my approximate time of ovulation would be Monday, July 14th. I know that taking birth control pills changes the time of "ovulation" and my body was telling my that my ovulation had occurred a few days before the expected date because I had increase vaginal discharge. I missed two pills (Saturday of the first week and Sunday of the 2nd week; I am a Sunday starter) I followed the instruction in the leaflet to make up for the missed pills. I had unprotected sex on July 13th which was the day before my expected ovulation day and again on July 16th and he pulls out every single time. (My boyfriend and I have been together for over 3 years and we have both been tested for STDs.) For about two or three days afterwards I had some brownish yellow discharge and abdominal pain(pain that could be because i'm either pregnant or because of my endometriosis). (My period is always a dark brown color- it is normal for me.) I have no nausea, no headaches, no sore nipples or darkening of them. Now I am wondering, with my endometriosis, vaginal discharge, two missed pills, and unprotected sex: what are my chances of being pregnant? I am expecting my period this Tuesday but the wait is killing me.
