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.

1) You've mentioned a lot in this service about a woman's menstrual cycle, and the risks involved with unprotected sex. Details that you have mentioned include, for example, the high risk of pregnancy (i.e., as a result of unprotected sex or failed contraception) during the "fertile period" of a woman's cycle. What I would like to know is: what (typically) are the various stages in the cycle (e.g., ovulation followed by menstruation, etc.), when do they typically occur in the cycle, and, most importantly, WHEN are the (typical, of course) fertile and infertile (minimum chance of pregnancy) parts of the cycle?

2) When calculating the length of your menstrual cycle, what is considered to be the actual first day of your cycle? Is it the first day there is "red" bleeding, or does it also include the first day or two of brown discharge?

What is the deal with menstrual cups? How is it different than a diaphragm? Is it safe? Is it safe for virgins to use? Is insertion much more difficult than tampons? How do you take it out? What are the benefits? I'd like an educated opinion.

My boyfriend and I are having sex 2 days after my menstrual cycle. I am on birth control. I finish my cycle on a Saturday and start the new cycle on Sunday. We usually have sex on the Saturday night before I start the new cycle. Is it safe to have sex even though you have finished your menstrual cycle but have not started taking the pill for the next cycle?

I have a somewhat embarrassing question. Is there anything specific I can do in my diet or anything to where my PMS bleeding flow isn't so heavy? It has been so heavy that at times, I put a tampon in and in a matter of like 20 min, I have to change in the beginning of my cycle. I also have had it leak into my clothing. This can be quite embarrassing. Any help would be appreciated.
