Hello,
I would like to learn or find out, the method of calculation of days is how much reliable?
Whether I can become pregnant in the first day after monthly (6 7 day of a cycle)?
Thanks.

Hello! The method of " safe days " is reliable on 55 60 %. Pregnancy for 6 7 days of a cycle is improbable, but is not excluded.
