Possible pregnancy

I’m never late for my period, the last time I’ve had sex was the 23rd of April 11 days ago the first time was the 16th of April. I was supposed to get my period yesterday I’m never late and I’m not stressed. On top of that I’ve been having nausea real bad where I feel I can throw up at any second, I’m tired af I’m always sleeping, I can barely get my classes done, I’ll cramp for a few seconds and then it quits. I bought two pregnancy tests but I was going to wait about 3 more days before I really worry. Please help!
