Should I be worried

Rosalyn

Ok last month me and my bf had sex and the condom broke and some of his cum was inside me FYI I have a skyla iud but idk why I was panicking not ready to be a mommy yet, need to be mentally and physically healthy and prepared to have one which Im trying to be I suffer from Bi-polar depression and anxiety and I'm just trying my best to fight this stuff.so anyways I asked him to purchase the plan b pill just in case the iud fails I have a back up. So he buys me it. The pharmacist told him that for me to take I right away so I did, a week later I puked I got my period earlier than usual. But this month I haven't gotten it in a day late having horrible cramps ,spotting , feeling nauseous, and super tired . Should I take a pregnancy test or wait it out until I get my period?
