Hmm, I know you said you didn't want anything like birth control, but I was wondering, does birth control actually enhance feminine features? And if so, would it be better to take it and miss many periods or not take it and still get them monthly? Is it the act of taking a pill everyday that would bother you? I ask this, because I have not experienced any effects from birth control other than lowered libido (thank goodness!). If it is just the act of taking the pill that bothers you (this may be worse, but bear with me) there is a thing called an IUD, and intrauterine device. If you use the hormonal one, it normally stops periods altogether. Though I think you have to go in to a doctor to get one inserted all the way into the uterus... so it stays up there like all the time. And it is expensive, or so I hear. As for the hormonal side effects, I read that once your body gets used to them, they kind of just go away. Sounds like a built up tolerance or something to me.
Idk if that sounds better than taking the pill, but other than that I don't know any other healthy options. I have heard that people who exercise too much lose their periods, but I feel like that can't be good for you. The pill I take now is a daily thing, but I only get a period every 3 months, so it is the bomb diggity. I wish you luck on your journey to find something that works for you!!!!
