Maulayia
I'm 6 days late my period was due on the 30 of March. I just got off the patch . My boyfriend and I have had unprotected sex multiple times last month . I went off of the patch in December and my period came on, so I'm thinking my period should have been on with me getting of the patch this month I had a period last month. I'm totally freaking out HELP
