QUESTION: i take the pil at 7.53 and i threw up at 12.. am i stil covered

ANSWER: that is 4 hours, the pill would likely digest in your stomach in that time. But it is possible for some of it to have come up. I would take your next pill on schedule, and I hope you feel better soon.

Thanks

QUESTION: when is a woman most feritle

Answer
The average woman is fertile for only 6 days out of her 28-day cycle. An egg can live only one day after it is released, while the longest sperm can live in the vagina is five days. A woman's cycle is dated from the first day of menstruation.

An interesting study in this month's British Medical Journal shows that only about 30 percent of women release their eggs to make them fertile from day 10 to 17. Even in women with regular repeatable menstrual cycles, most women reach their fertile days earlier and many much later. Because of this extreme variability in egg release, most women need more than the rhythm method to prevent pregnancy.
