I am a 31 yo female and have an issue. I should be on my period and I'm not. I have not been sexually active at all since the end of Dec. I was on BCP at the time. I have experienced a lot of bloating, constipation and dizzy spells. At times I am very fatigued and others I have all the energy in the world. Generally I don't have much of a period at all, but since I stopped taking my BCP a month ago (forgot my refill so wanted to start after my period), I should have a normal one - and I am 2 days late. What could be the problem?
