Scared

King • 22. Young. Taken. In love. No ring yet. Just trying to get double Mj. No time for babies. But enough time for no babies
I missed my period by a week.. This rarely happens. It's been 5 weeks now. But In the 5 weeks I went off a birthcontrol and started a new kind. During that time I had sex, unprotected, but he didn't finish. Likelihood?
