I've been taking birth control pills for almost seven years and decided to stop taking them as of my last cycle last week. What kind of changes should I be expecting? How long will it take for my body to get used to not having the hormones? In the past few days, I've been feeling very edgy, tired, and with on and off headaches. Is it true that once you withdraw from birth control pills, you may actually lose a few pounds?

I know that some women do get fevers as a part of their period, but is it normal to get high fevers? I have never had a problem with my period before, but the last two periods have had me chilled, feverish, and with a temperature of up to 102 degrees Fahrenheit, I couldn't even go to work or anything for like a week. I don't use tampons, and I'm not sexually active. I am in pretty good shape. Please tell me I won't have to take a week off of my life every month from now on because of these awful fevers. Is there anything I can do?

I'm a man and I'm engaged in a lot of sports and outdoor activities, but lately some of my friends said that biking could result in male infertility. Is this true? How? What are the other activities that could lead to male infertility? How can I stay healthy in terms of fertility?

Okay, so my mother does not believe, as I do, that when a group of women live closely together (i.e., in a dorm setting) that their menstrual cycles become roughly similar, due to the release of pheromones. I'm pretty sure that I heard this somewhere, but I can't find anything to back it up. I swear I'm not making it up, but my mom doesn't believe me.

Thanks for your help.
