Can you get pregnant while on your period?
The chance of getting pregnant while having your period is decreased. But, there is no such word as impossible when it comes to avoiding pregnancy. Women who seek to use their cycles to avoid pregnancy may face poor odds.
Data on tests of 213 women during almost 700 menstrual cycles concluded that even women with normally regular menstrual cycles should be advised that their fertile window can be significantly unpredictable. Researchers at the National Institute of Environmental Sciences found that only about 30 percent of women actually have their fertile period between days 10 and 17 of their menstrual cycle. They found that the potential for fertility exists on almost every day of a woman's menstrual cycle. Fertile days were found to be most unpredictable in younger women (under the age of 25).
These results from the National Institute of Environmental Sciences were described in 2005 in the British Medical Journal.
Using a contraceptive method is strongly advised, even during your periods.
