help :((

so my period is late by three days. i had protected sex like, once or twice earlier this month. he only came once, and it wasn’t inside of me. neither of the condoms broke. my boobs haven’t been as sore as usual, but i’ve definitely been emotional like always am before my period and i’ve definitely had a big appetite. i’ve also been really stressed recently and i’ve been breaking out.. any ideas as to what’s been happening?
