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?

My wife and I had our first child last July. Until about 3 months ago, she was unable to reach orgasm at all. Of late, she has very small one's, but they don't seem to be getting much better. Prior to having the baby, she had strong, very quick (3-5 minutes) orgasms 90% of the time. I know the stress of being at work rather than home with the baby could play a part in this. Is this common and is there a way to mitigate the problem? 

If one has a long-term partner and neither AIDS nor any other STD is a concern, is there any medical reason not to perform cunnilingus on a menstruating woman? My significant other is particularly horny during her period and would love cunnilingus at this time. I am willing but curious.

I'm a 19-year-old female. I had my right ovary removed (oophorectomy) three years ago due to a very large ovarian cyst. I was assured by my gynecologist that I'm still capable of bearing children but wasn't informed thoroughly of all of the pros and cons in regards to this type of operation (e.g., can the estrogen loss have any negative physical affects?). If you could shed some light on this matter, it would be greatly appreciated. Thanks.

I'm wondering if washing immediately and throughly after intercourse helps prevent pregnancy.

I have been having this problem where my period will not stop. My period is usually not regular — I won't have one for about two months and then I will have one for about a-month-and-half, but this time it is hasn't stopped for three months now. What do you think I should do? I would really love to know what is wrong.

I recently saw a flyer in one of the public restrooms at my college claiming that tampons contained harmful synthetic fibers that can cause cancer. Is this true?

Is it possible to get pregnant when I am a lactating mother of a three month old baby and I missed my period this month? Last month, I had spotting — like I have periods for two days for the first week and second week of the month. I’m worried about getting pregnant again. Please help me; we had sex two days after my spotting/period.

I have two questions, first: On my birth control pill box instructions it says to take a pill each day at ABOUT the same time. I was wondering, does this mean that I should set an alarm to make sure I take it the exact minute every day (which is what I've been doing) or can I take it within a couple of hours difference if I decide to sleep in on Saturday?

Secondly: My doctor told me that if I miss a pill to consider myself unprotected for that month. However, after I left I realized that in biology class we learned that a ovum (or egg) can only survive a few days inside the fallopian tubes and uterus and then it get absorbed into the body (or dies). If I missed a pill then wouldn't I only be unprotected for the next couple of days (if an egg was produced in the 24 hr period that I didn't take the pill) instead of the whole month?

Do you and your husband both have to orgasm in order to get pregnant?

Could the birth control pill be causing my weird food cravings?

Do you have any information on the effects of low testosterone concerning sexual desire in women? After I got pregnant, I have had a significant drop in sexual desire and think it could be related to low testosterone. Any info on the subject? By the way, this problem had nothing to do with stress, marital problems, or the baby. Everything in my life is great except I lost my sexual desire and want to get it back. THANKS.

What is the usual treatment for missed periods? I haven't had my period for half a year (ever since I stopped taking the pill). I have also lost some weight. What are the health effects of missed periods?

I am really nervous because my period is a week late so far and I am studying abroad in Egypt. I really don't know who to talk to about this. Premarital sex is a big taboo, abortion is illegal, and I can't even find a pregnancy test at a pharmacy. What should I do? I can't come back to the U.S. with a big belly — I can't tell my family! I am so afraid! I left the U.S. a month ago (my partner is still there). I read that jetlag can influence your menstrual cycle, as can weight gain or loss. I was jetlagged, but my weight is more or less the same (except I am eating more rice and oil than I do normally). Could diet change your cycle? Anyway, I guess my main question is, what should you do if you find out you are pregnant in a conservative country where abortion is illegal and don't have enough money to fly home and back? Thanks.
