I'm 19 years old and my last period was March 24-27th. I stopped birth control in November 2011 because it was causing blood clots. I was taking it to regulate it, and since I've been off its been quite irregular. But I have never been THIS late. My boyfriend and I are very cautious and typically always use a condom, but there have been times when we have been unprotected. I have taken several HPT that all have come out negative and even have gone to a pregnancy center where the tests are quite accurate and it also came out negative. Is it normal to be this late?
Maybe you ovulate irregularly.
