Boyfriend ejaculated then got his fingers near my pelvic area. My period was late for 9 days so i had 2 home pregnancy test & a blood hcg test all came negative. I got my period on the 9th day. I also got my period the month after. So on the 3rd month i had another home pregnancy test and still negative. But my nipples are sore and i feel fatigue. Is there a chance I could still be pregnant?
