I'm already 22 years old.. and me and my boyfriend is in 2nd yr of our relationship. We always have sex before my period and after (5 days before and 5 days after rule). My cycle is regular, means I'm having it every month. The rule never fails us (even my friend and his bf). But this month, I had a lot of issues to deal. Do you think I'm only stressed? I had my home-test and its negative. This same scene happened to me last year and I still had my mens after 2 weeks of delay. Now is my 11th day of delay.
