Hello. I am 28 years old and I went off birth control in September 2008, after being on it for 12 years. I had a regular period 6 weeks later (ending on Nov.1, 2008), but not one since. So, it's been about 7 months. I've taken many home pregnancy tests, all of which are clearly negative. I have no symptoms of pregnancy, either. I've done some research on the internet and this seems to be a fairly common thing after going off the pill. I have gained about 15 lbs over the past several months, but I also quit smoking a year ago and I haven't been doing Weight Watcher's or exercise like I had been the past couple years. I haven't been to the doctor yet, but now I'm wondering if I should. I guess since I feel absolutely fine, I don't think about it. What would be your opinion? Should I go to the doctor or is this something that I can wait out? Thanks so much!

I'd say go to the doctor.
