I have a regular 28 day cycle period usually last 3 days, third day being the lightest. ovulation occurred march 26-31, period was supposed to stars?

28 day cycle: Since you count cycle length from the first day of one period to the first day of the next,if you have a 28 day cycle your period should start 28 days after the last one started.This would be 14 days after ovulation or, in this case, 4/9/15.Remember, however, that some variation is normal. If your period hasn't started yet,it is time to check a pregnancy test and repeat it in 3-5 days if it is -.
