I am married since 2015, but recently since one month back we have started our family planning and having unprotected intercourse nearly 7-8 times in a month.. and during fertile window days had 3 times intercourse. As due to lifestyle till these years we used to have sex only on weekends protected. I want to understand is sex during ovulation cycle only helps to be pregnant?? And how often we need to have intercourse when we are trying for a baby.. as both of we are mgt. Professionals and working.
