I m 20 years of age. I got my last period last April 10. My boyf and I done the deed April 20&21, but not continuously cause were on a outing. And we did not use any protection, tho he did pull out before he come out. Then I should have my period this May 8. I have a regular cycle for the past months. My breast are sore but usually, it is normal if i will gonna get my period. Brown discharge is present since May 6. So I though, I will gonna have my period already. But im wrong. Also, my time routine just changed because of school. Been stressing about school lately. What should I do? Could I be pregnant?
