I had sex with my boyfriend and we used a condom and spermicide. The condom did not break or tear and it didn't leak into me. I was supposed to get my period within the next 4 days and I never got it. It's been over a month since then and I still have no period. I have not had any symptoms of pregnancy. I am pretty sure I ovulated about 12 days ago because I was keeping track of my cervical mucous and it was clear, stretchy and there was a lot more of it, and I woke up with pain in my lower abdomen on one side, but it only lasted about a half hour. If I am correct I should be getting my period within the next 5 days, plus I feel the symptoms I get right before my period coming. But I don't know if I should be worried or just keep waiting? Is there any chance I am pregnant? Any advice is appreciated
