i have had stomach pains for the last week and can't figure out what is wrong. i have also gained 2 inches in the last 2 weeks. at first i tought i could be pregnant so i took a pragnancy test and it came out negative. i haven't changed any excercise or eating habits either. i do get a lot of cists on my ovary (i had a 40 lb cist taken out 2 years ago and it destroyed my left ovary). i have had my period every other week (week long) for all of april and may than it stopped and it should have been back acording to the calendar but it hasn't come. do you think it is another cist growing that is causing all of the pain and weight-gain?? and if so, to get rid of a 7 cm cist last summer my dr experimented with me taking birth control to get rid of it and 4 months later it had almost disappeared and i stopped taking them. there is a prescription for them left, should i just start taking them again?
