i had unprotected sex a little while after i messed up my birth control and took it mid cycle. ive read this can make you more susceptible to pregnancy. my boyfriend did not come in me but im still extremely worried.its been about two weeks since the sex and i feel like im gonna get my period and its kind of around the time that i should.ive been stressing about this, and i need to know how big are my chances of being pregnant. and can i take a pregnancy test yet?
