am I pregnant?!!!

I had unprotected sex 6 days after ovulation. I'm not 2 days late on my period. the few days after sex, probably 4, I had very bad cramping. and then just light since then. but the past 2ish days I haven't had cramps. I have had bad bloating and I have been tired. I think it's too early to have real symptoms but the cramps and bloating worried me. what should I do??
