I am 20 years old i do have unprotected sex with my boyfriend . But lately i've been getting sharp pain in my stomach by my belly button or on the sides and it's only for a little while then it stops. I have also been feeling really sleepy thru out the day not to mention i don't eat as much i feel disgusted by many foods. & i did get my period this month but not like other times , i usually get it for an entire week & this time it was less days & light.
Having unprotected sex heightens your chances of pregnancy a lot. You could be pregnant but your best bet is to take a pregnancy test. Depending when you had sexual intercourse, you should wait about 10-14 days to take the test.
