My sister has a period every three weeks exactly.?!


Question: She has had a period on the 20th december, she counts 4 days from that so from the 25th of december she counts 21 days which means she is due a period on the 14th or 15th of January. Now can any one work out when is her time for ovulation, ie when she should concieve. This is for the time between the 25th Decemeber and 15 th January. Thanks guys me and my sister are no good at this ovulation thing.

about 10-12 days after her period stops so...now.

the middle day between first period days..

what does she want a medal?

wear a condom if she doesnt want to concieve, or you could go to your docs/ family planning clinic and get a period chart it tells you when your most fertile

Its 10-12days after the 25th so she should be getting active and haven playtime now if she wants get pregnant but at the end of the day, sperm only last 5days for girls and 7days for the boys so my quesses is start now and keep going till the 15th, defly should fall preggers. goodluck
