If you have a 28 day cycle, ovulation
normally occurs around the 14-15th day. Can ovulation
occur earlier and if so how early can it occur. Reason being I am trying to get pregnant....not sure if I already am but my 1st day of last period was Feb 13 and I have been bd 14,17,19,21,23. I guess I am scheduled to ovulate around the 26-27. Need some advice.
