Help (nip info)

So ive been having unprotected sex with my partner for about a month now almost everyday. I have inverted nipples, sometimes I can make my left nipple hard and poke out, but I’ve never EVER been able to get my right nipple to poke out. And the past couple of days she’s been coming out. It’s a Christmas miracle! My nipples like, like regular nipples for the first time in my life!! I should start my period on the 17th but I have a feeling that this is happening because maybe I’m pregnant? Please tell me what you think. It’s too soon to take a test, I’ve tried and it came out negative. I don’t have the patience to wait till the 17th to find out!
