Really want my period to come so badd

So the other day I went to go get my physical or like check up so that I can play sports or whatever for my school .... so back in July I did some rubbing on my like but kinda like anal but not because I was never entered I’m a Virgin is token multiple preg tests all beg and I have gotten 2 periods since accept the last one only lasted 2 days but was heavy with clots .... the stress has also made them irregular... and when I went to the doctor and he made me lay on my neck and felt my stomach for any lumps and there was none and he checked my pulse in my stomach and made sure that it was the same pulse everywhere else my next period is in 6 days according to my last one but like I said stressing over this had made them irregular so idk I’m just scared I wont get it (also when i went to the doc for a check up I would be about 13-14 wks )
