My bf & I had sex either may 15/20 on June I got a 2 day PD this month I got a 1 day PD that lasted 4hrs. I haven't taken a pregnancy test but could it be possible or is it just an irregular PD....tho I am exact every month and my PD las 5-7 days......should I be worried or no. Can someone tell me what was their outcome if you was in my shoes pls.
