It's possible, but there's no sense in stressing about it. How long ago did you have intercourse? It's possible that is the culprit for your cramps.

last sunday

Hmmm....just wait it out. I had mid-cycle cramps this month and I am not pregnant. Sometimes it just happens. Take a pregnancy test the morning of your period if it does not come.

well i have an ireggular period,soo i dont know when i will get it

When was your last menstrual period?

How old are you? How long have you been having your period? ( 6 months?, 2 years?, etc., etc.)

im 16,and ive had my period for 3 year,i cant remember my last period : /

its been a week since intercourse,or attempted intercourse i should say

test f ur late on ur due period...its very important to remember ur last menstrual period especially when u r having intercourse

Well, the best advice I can give is to test 14 days after the incident. (this is assuming there are no other incidents of unprotected sex.)

its called a penis btw

and i doubt it
um cramps? wow that can be a million things

get on birthcontrol

kthnxbye

oh and you wouldnt be haveing any symptoms in a week
