Pregnant

So, I had unprotected sex on the first two days of my fertile window (April 20-21) and the guy wasn’t sure if he came in me (apparently has no feeling in the head of his penis and is allergic to latex which is why no condoms were used) I am not feeling normal, I’ve been getting small random cramps in my uterus and hips, my discharge was off colored for a few days and has since went back to normal. I’ve taken two tests so far and am supposed to start my period on the 9th of May. Any suggestions on when is the appropriate time to worry or take more tests?
