In 28-days woman cycle what her exact safe days?
Be careful if you have counting on finding the exact safe days.
Each woman is different and our cycles are different.
Usually the best time to get pregnant is around 2 weeks after you have started your period. Some woman have a 28 day cycle, some a 30 day, some 31. I would not use this counting method as a method of birth control( unless you are want a baby)
there are no exact safe days. I always thought you were safest when on your period but I got pregnant with that theory. Always use contraceptives if you' don't want to get pregnant.
You need to chart three things: your basal temperature, your cervical mucus, and your cervical position. Look up Fertility Awareness Method on the internet. There are certain times when your body cannot get pregnant because you are too far from ovulation, but you can't track this down on a calendar. Everyone's body is different, so you have to look for your own personal signs of ovulation. The "calendar method" is notoriously unreliable!
Like answerer #1 said, there are no exact safe days, and even contraceptives aren't 100%, my son is a "pill baby" , and I swear I never missed one pill...ever!!
