If I don't take birth control pills at exactly the same time am I unprotected?

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?


How often should I wash my hair?

The last time I was at the hair cutting salon, the person who washed my hair asked me if I washed my hair everyday. I said I did, and she said she could tell. I'm not sure what she meant by this, but please tell me how she could determine this, and what is the best overall practice for washing hair in terms of frequency. I'm interested in the health of my hair as well as the health of my scalp. Thanks for you help!


Can lowered testosterone levels in women reduce sex drive?

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.


Why is my wife losing hair?

My wife has noted that she is recently losing hair at a much greater rate than normal. She feels her hair is significantly thinner (less density of strands) than in the past. What could be the cause of this?
