Uhh I’m late.

Okay, so my boyfriend and I had unprotected sex on February 8th, and he pulled out and all. Todays the 13th, and I haven’t felt anything for my period, no cramps, no discharge/smell, etc. Last time I got my period was January 16th, to the 21st. I know 5 days isn’t enough time to give, but I’m worried. My period also don’t regulate, so sometimes it’ll be at the beginning of one month, then the end of the next. But I’m still scared. I’m eating a lot. My stomachs getting a bit bigger (because of how much I’m eating, obviously lmao). And I’m craving certain foods a lot. Am I just being paranoid? Should I get a pregnancy test incase and take it if I don’t get/feel my period in the next few days? I don’t know what to do and I’m scared.
