I had sex for the first time 3 months ago. When my period was late after I have been stressing about it for a while I took a
pregnancy test that came out negative. After I calmed down some my period came on the 10th of march. The next month my period came the 9th of April. But this months my period still hasn't came and it's the 13th of May and I have been stressing about that because my period has always been regular. Am I just stressing myself out and causing my period to not come or what? I'm 18 years old.
