Hello, my name is Sabrina and I am 34 years old. I was diagnosed with endometriosis about 8 or 9 years ago, and I have been on Yasmin ever since to control the symptoms. I actually haven't had a period for many years...I can't even remember the last time I had one. I occasionally have very mild menstrual cramps at that time of the month but I haven't had a trace of menstrual blood for a long time. I thought that one reason was probably because I am obese...right now I have well over 200 pounds to lose, and I have gained most of this weight steadily over the last 7 years since my sister was killed by her boyfriend. That tragic event in my life contributed a lot to my weight gain, but I have struggled with my weight all my life. For the last week I have been on the Dr.Poon diet, which is a low carb, low fat diet, and I haven't had my first weigh-in yet but I am certain I have been losing weight because I feel so much better in just a week, and I can tell in my face I have lost some. So my body is changing a LOT right now....but one change I didn't anticipate was getting my period!!! I am completely baffled, I just discovered it about 20 minutes ago and I came straight here to post LOL! I haven't posted on these message boards in years! But I am curious if anyone might have some insight into why all of a sudden I am menstruating!!! My gynocologist said that hormones and obesity could play a part in why I haven't menstruated in so long but mostly it's because I'm on the Yasmin for so long. Maybe it's just a coincidence, but I'm willing to bet that the diet is changing more in my body than I realized!!! Any thoughts?
