I had intercourse two months ago in March. Although I know it is not a fool-proof method, my partner did not ejaculate inside. A few hours after, I rushed to the drug store and bought Plan B and took it as directed. Since then, I have had two regular periods. Right now, I'm about due for my next period but I've been reading other pages online that say that you can have two periods and still be pregnant. My breasts are sore, which is a usual PMS symptom for me, but I'm worried about my weight. I have been depressed lately so I could be eating more than usual (or not eating the right foods), but I'm worried. Am I getting paranoid or could I be pregnant?
