my period isn’t due for another week. i just moved into a house with other girls last month.

i had sex about a a week and a half ago .

i am spotting, feeling crampy and bloated.

could it just be my period syncing with the other girl who just started her period or should i get a pregnancy test ??

side note : i did not use a condom, used pull out method and also took plan b pill . (i know pull out method doesn’t always help)
