I have been on the Nuvaring for three months now, and I am keeping it in for the four weeks then changing it because my doctor said there's no need for me to have a period. About two weeks ago I started having dark brown discharge and it has gotten more heavy, but only when I run or stand up real quick. Is this normal or should I call my doctor and find out what is going on?

I seem to feel more strongly sexed (hornier) than usual during my menses and so do some of my girlfriends. Is there a clinical explanation for that or are we just weird?

I have had a notebook (laptop) computer for three years now. I never use it on a desk, but rather surf the web with it sitting on my lap. Since I am only 18 years old, I worry that someday I may try to make a baby and fail. Could an electronic device such as this sitting above my testicles every day lead to infertility?

Is it possible for nonpregnant women or women who have never been pregnant to lactate? If so, what would be the best way to stimulate in a safe, healthy way? I'd love to please my new husband with this. Are there any draw backs?

I have recently been advised that my on-going migraines might be caused and/or increased by the use of contraceptives containing estrogen. To that end, I have been recommended to switch to a progesterone-only form of birth control. Which, in turn, basically means I get to choose between Implanon and Mirena (I really can't stand needles, so Depo is out for me!). I am only 23 years old, and have not yet started a family. I do want to have children someday, and am very enticed by the idea of Mirena lasting to the point when I might want to begin trying to get pregnant. However, all of the advertisements for Mirena state that ideal candidates have already had children.

Is Mirena still safe for use in women who have not yet given birth? If so are there any additional side effects to consider in this instance?

I am not sure who the father of my son is. Is it possible to tell the father of the baby simply by knowing blood types and Rh factors of myself and the potential fathers?
