Hello. I have a question. Last month I was on my period for two weeks. During the entire month of November, there was no period. I have been sexually active nonstop, even towards the end of my cycle when I began spotting. Now I am not sure if it is due to hormonal change considering the fact that I was on Depo from May 2015 until August 2015. I also have history of irregular periods before getting on Depo but my menstrual cycle became regular while I was using depo until now. Could I be pregnant?
