I am trying to concieve but have a problem. It is hard for me to track my days on a calendar cause going month to month is hard since my period is a different amonunt of days. one month it could be 28 days then the next could be 32 days. so how do i know when its best for ovulation?i look at my cm and had sex on those days that it was egg white and milky stretchy like and still not pregnant. anyone who can help?
