my boyfriend and i had unprotected sex the day before i was due for my period. i started my period on april 2. thought i was finished on april 6 and had unprotected sex, but iwasnt finished. then the 9the came around i was finished and we had unprotected sex again. now i am cramping really bad like my uterus is squeezing in and out. it doesn't hurt all over all the time it hurts in spots sometimes. this has been going on since last friday. is this a sign i could be pregnate and when is the best time for me to get a test to find out if i am. i have had one child he is now three. i didnt show signs with him until i found out i was pregnate. what does this mean?
