Hi, last year i was on medication to help myself lose weight, Reductil. I had lost 3 stone within that year and came off my medication back in September. My periods have always been regular and i had a period back in October 2009. Since then i have piled on the weight and have now gain 4 stone in such a short time!! I haven't changed my diet and i've had blood test done on my thyroid which came back borderline and after a month i had another blood test and my thyroid was back in balance. They also tested me for PCOS which came back fine... by this time i still have not had a period so they sent me to have an internal scan done to rule it finally. The reason why i wanted to lose weight was so i could try for a baby this year and now i don't have regular periods? I had another period towards the end of March and we are now in June and still haven't period... i know that i am not pregnant and i feel that i will never concieve... i'm very depress and need advice!! Please help, Lucy age 22.
