So I had sex. Twice unprotected. The first time he didn’t even cum because I was scared so I told him to stop because we didn’t have protection. The second time he pulled out but I don’t know if he fully pulled out and he said he barely even busted. This was all three to two days before my period. I’m a day late. Today making it two. and stressing out. Do you think all the stress from “I could be pregnant” is stopping me from getting my period?
