I was on the birth control shot for three months and had a period a week June 17-20 before my next shot was due and I missed my shot and have not had another period sense June 20 2010 and have had unprotected sex could I be pregnant or is it from the birth control

The best thing to do is take a test. I was on the birth control shot when me and my boyfriend decided we wanted a baby so I stopped having the shot and I got pregnant within a month.

Everybody is different though so go to the docs or do a test x
