Hi im 27 and my boyfriend had a vasectomy with his now ex wife about 7 years ago, I have a little girl of my own who will be 7 so its been a while since i know what to look for if I'm pregnant. But my breast are very sore, im very nauseated, sometimes light headed and cramping. Im tired and moodie. I normally have a 48 to 53 day cycle, but I'm 5 days late.... When we have sex he pulls out; so I'm wondering could i possible I'm pregnant?
