Husband and I had unprotected sex.....✨

We had unprotected sex about 2 weeks ago. Well I wasn't ovulating that day but the next day I was ovulating. Well he went in me so now I think I might be pregnant? Im starting to have like lower cramps and my ovaries have some mild pain.  Just weird. I'm suppost to start in 7 days and my breast are killing me!!!!! All I wanna do is eat and sleep! lol something is up for sure! Anyone experience this ?
