Help!!

So my period always comes every 2 months on the same day at the same time . My last period came rather early. But, it's been since March 14th since my last period and I was expecting it to start up early into this month like last time or how it usually is (aka around the 22nd. Today's the 23rd) . I've been waiting for it and I'm late.. I had unprotected sex last week but he pulled out and I talked to him again and he swears to me that he did. I'm afraid I might be pregnant or I'm probably just late, I don't know . I've been breaking out all over my face bad this week & I've been craving so much sweets like crazy. I got mild cramps yesterday, nothing bad. What do you thinks the problem ? Please help a sister out lol I'm driving myself crazy basically thinking I'm pregnant or something. Please share your thoughts !!!
