Okay so me and my boyfriend had sex a few weeks ago and the condom came off when he withdrew or slipped off while we were uhhh...anyway if it did just slip off when he withdrew could I be pregnant the condom was in me, or on my vulva/labia and I had a 2 1/2 day period I usually have a 5-6 day period and it was late a few days before it came I had some weird cramping I usually only have cramping on the day my period was gonna start, I have been feeling nauseaus tired, but I usually am anyway, and my stomache has been hurting....like cramps, no breast soreness...though they are more sensitive, when I eat or drink like at the moment I am drinking pepsi and it is uncomfortable not sure how to exlpain it. Also I have been pretty snappy and mood swings like things that normally wouldnt bother me so much I would be like grouchy or easily irritated....I am not sure.
