I was told the best time to get pregnant is 11 days from the day you started your period
. So start counting the day your period
started .... up through the period
... until you reach 11. I know not all women are the same, so this could vary some. But this was what I was told by several people who were trying to get pregnant. They said that the 11th & 13th days were the best.
So, if you are trying to avoid getting pregnant ... then I would avoid sex on or around these days.
