I am married, 20 years old, only had one partner, no children. Took the BC pill for about 2 years before stopping it (at the end of a pack) in October '07. Since then, I've only had 4 periods and my last one was... (my calendar is not in sight so I might be a week or two off) about 12-15 weeks ago. A really long freakin' time. Each one of my other ones were about 6 weeks, then 8 weeks, then 10 weeks, etc, apart.

I lost about 20 lbs (from 160ish to 140ish) from March-July '07 (went to Curves and stopped stuffing my face). I stopped taking the pill in October, and am now currently at around 125 lbs. I burn about 300 calories per day on my elliptical but I eat regularly, probably about 1300-1500, not counting what I burn. I am not the world's healthiest eater but I get a lot of protein, whole wheats and grains, just not a lot of fruits and veggies.

My husband and I are both in college and while I am a nanny, he works for a very small company with no benefits. He is currently trying to find a job with benefits so I can see a gynecologist about this. However, I am really starting to get worried. Should I be? What could be the cause? Has this happened to anyone else?
