Pms or something else?

So it's almost 3 weeks since my period. A week and a half since ovulating. I'm feeling crampy and bloated...Google said it might be my body becoming pregnant since it's still another 2 weeks until my period and I normally don't start having cramps until a couple days before the first day of my period. Am I just getting my hopes up? My SO and I had sex every day in my fertile period and I've been taking prenatal vitamins and drinking fertile tea every day. I really hope I get pregnant this time around.
