vaginapagina | Lack of period question! (Reply)

Hey everyone!

I suppose it's time to start to wonder about this.
I didn't get my first period until I was seventeen. I saw a OB/GYN at 17, and they gave me hormones to make my period begin, and then I was immediately put on birth control which I took for the next 4 years. Thus, faithfully having a period every time I was on an "off week" with the BC.
(I've been on ortho, yasmin, and most recently ortho evra if anyone cares :o)
I stopped taking the birth control in December, I was no longer married, no longer sleeping with men at all, and my insurance was done. I got my last period in February, and it's been absent since.

To clear up a few things: I haven't had sex with a man since October. I'm of a normal weight, my BMI is 21 or 22. I'm not under abnormal amounts of stress, so I don't think that's what is stopping my periods. I don't especially WANT a period which is why I haven't felt pressed to "fix" the problem, but I'm wondering if anyone has any idea what would make a woman only capable of having a period while on birth control?

thanks, any insight is appreciated.
