ttc 😍😍

Ive recently been trying to conceive. Today is September 30th, about 2 days ago September 28th I was ovulation. On my 4th day of ovulation, I had unprotected sex. Today I was a weird feeling in my stomach, kinda like cramps but then just kinda fluttering in my lower stomach. I've been gassy and burping and having the urge to gag. And throw up but nothing comes out. Could I possible be pregnant?
