Ok, on May 11th, and on May 13th, I had unprotected intercourse one time on each day, and he came near my vagina both times (some was running down the part of my leg very close to the vagina, sorry to be graphic). My last period started April 25th, and my cycles, I think, are 31 days long. For the past 3 or 4 periods, my period has come 2-3 days early, so my cycles went from 35 to 31 days, but they have had time to regulate and they have been regular for the most part. I calculated when I should have ovulated this month, and the date was May 12th, which isn't good because I had sex 24 hrs before and 24 hrs after I supposedly ovulated. My next period is supposed to start around Wed. the 26th, which is in 3 1/2 days and I have no signs of a period starting. I didn't realize this until today, but normally I start PMSing a week before I start, my boobs and nipples are just barely sore, normally they are hurting pretty dang bad before I start and thats one of the things that gives it away I'm going to. Last week,I was very bloated and constantly dizzy. I've been having dizzy spells at work and stuff which seems unnormal to have them so often. One morning, I felt so nauseated in first hr at school that I almost called home. I had to put my head down and try very hard not to think about it. I have an EPT HPT, so when should I take it? Should I wait till this weekend and see if my period ever starts? Does it sound like I'm PG? I haven't been stressing over it so I know I'm not making my period not come, but I'd really like to hear ANYONE's opinions! Please respond ASAP! Thanks sooo much!
