Patient: I have not been on birth conttrol for about 2 years now so I know this problem has nothing to do with that but for the past year I have had very irregular periods and now they have seemed to have stopped altogether. I have not had a period for over 5months now amd I have done lots of pregnancy tests and they have all been negative. What other reason could there be for not having a period and also can I still get pregnant if I’m not having periods?
