I have read a lot about irregular periods and pregnancy and it seems to all be on the fence. When I am on bc my period is a regular 28 cycle. However I came off of my bc back in Dec. for surgical reasons and never went back on it because I wasn't sexually active for that time. However, I had unprotective sex. My boyfriend at the time had not put on a condom and I had thought he did. (Please no lectures about unprotective sex I am old enough to know the effects and what you can do to prevent it.) I have had some symptoms of pregnancy like heartburn, nausea, tenderness, and dark reddish/brown spotting. However, since I haven't had my period since Dec. I am not entirely sure when I should test or if it is still possible to be pregnant. If you have any advice please let me know. Thanks
