I Haven't had a menstrual period in 7 months after getting off birth control, Can you tell me why?I have pretty much always had irregular periods they came every 3 to 4 months, my doctor said its not normal so I started birth control. I was suppose to be on it for a year and then see if it would come on its own. I was on it for the first 6 months and stop to see if it would come. It did for about 2 months and then it stopped again. I finished my prescription and got of the birth control in november of 2010. My cycle came every month till febuary or March of which was when I had my last. Since being off of them I haven't had a cycle, it seems like I get symptoms like bloating and some light cramps for a few day like its getting ready to start but that's it. I'm only 18 and not sexually active,I was also tested for thyroid disease twice by a new doctor and she said the test were normal. I'm very scared that I wont be able to have children later on in life, is there any thing I can do?
