Pregnant or am I overthinking?

So, lemme rewind

2 months ago my boyfriend and I had unprotected sex, he didn't cum inside me, but I was anyways and clean it all up anyways.

So my last period (July 22) was one day, heavy bleeding that leaked through to my pants (😫😫 ugh) and then the next day some brown blood but nothing more, I had cramps, the whole nine yards. Note: my periods are normally 2-4 days so I feel it was a little usual for me idk.

I guess I'm just worried that it was normal, my period is now 2 days away, and I've been having cramps, and I think PMS but I still worry, and I guess maybe some other ladies (aside from myself and friends) that I'm gonna be all good, I don't think I am but there's always that looming feeling this last month and it is driving me crazy... Please tell me I'm crazy y'all!!
