no 'safe' time to avoid pregnancy

No 'safe' time to avoid pregnancy:

For 50 years, doctors have believed that about a dozen follicles, or egg sacs, grow at one time during a woman's menstrual cycle. From this group, only one follicle actually bursts and releases an egg, while the others shrivel and die.

But, in a finding that left even researchers "flabbergasted," University of Saskatchewan scientists have found this pattern of follicular development actually occurs two to three separate times during a woman's menstrual cycle. What's more, 40 per cent of women have the biological potential to ovulate more than once during a cycle.

Has anybody told the Pope?

I think Robert A. Heinlein said it best. "Doctors have a word for women who rely on the rhythm method. They are called 'mothers'."

From Time Enough for Love, IIRC. It's been about 25 years, so I may not have the words exactly right.

Many women experience a little pain w/ ovulation, so they frequently can tell when it occurs. Periodic double or triple ovulation is quite common.
