vaginapagina | Pregnant while having sex on my period?

hello!

so, my periods are very light. they only last about two and a half days. the first day it is really heavy then the next day its very light and the the third day its hardly there at all.

my boyfriend and i decided to have sex on the second day of my period, where there was SOME blood, but it was not very gross.

for some stupid reason i thought it was impossible to get pregnant while on your period, so he came twice inside of me (the first time anyones ever done that to me).

i also took plan b the next day--but i am FREAKING OUT. when should i get a pregnancy test? also, i have an appt for birth control tomorrow.

gahh im freaking. thank you SO MUCH in advance.
