Fertility calculator & calendar

Fertility Calculator & Calendar If you've got your period (when you were really hoping it wouldn't happen) stay positive. Just think, if you do conceive this month, this will be considered week one of your pregnancy. Right now, your body is shedding a combination of the lining of your womb (called the endometrium) and actual blood. You won't know whether your egg has been fertilized for another month, but can still do things to focus on your Fertility Calendar .
