ive been having regular unprotected sex this past month and im sure of one time my bf ejaculated in me, so there’s a chance i could be pregnant, my period is to be due in 4/5 days, yesterday i had very very light pink blood when i wiped today the blood is much darker and it’s there when i wipe, also a few drops on my underwear, I’ve put a pad on to keep an eye on the blood and there’s just a tiny blood stain, what do you all think?
