I’m not pregnant but uh, maybe I am?

I am 99% sure I’m not pregnant and I need you guys to reassure me.

The last time I had sex was admittedly unprotected and near ovulation (because I like to live on the edge, ok?) BUT I’ve had my period since then.

Or so I think.

So the sex was aplenty back at the beginning of March, then I moved away and since then the sex has been completely nonexistent. I got my period in the middle of March- it was early, which was weird. My periods are never early. It lasted 6 days, one day was heavy enough to soak a pad but the other days were light. Usually my cramps are debilitating for at least one day, and these cramps weren’t nearly as bad (but still there).

Now my period this month is 5 days late. I’ve been cramping for daaaayyyyysssss like my period is about to start and it is nowhere to be found.

There is no possible way I could be pregnant, right? Please talk me out of this scare.
