3 week mense

  I'm curious as to when ovulation would occure during a 21 day cycle?
  I had to take clomid for my first child.  I concieved the first month.
  My husband and I have had protected sex since this birth 2 years ago.
  My periods have varied from 21 days to sometimes 28 days.  I always spot for 3-4 days prior to heay flow and then that last for about 3 days.  I started spotting on the 10th of Feb. and finished completly onthe 16th. We had unprotected sex on the night of the 20th.  Recently my breast have become tender and swollen, darker veins and arolea, and milky buds on the nipples.  I've also noticed a sharp pain in my abdomen.  I haven't felt any more tired.  I wasn't keeping track of any differences in discharge.
  I'm anxious to know when you think ovulation would have occured and is spotting considered part of my period?  Thank you for any insight you might have......Kathy

Dear Kathy:
The first day of a menstrual cycle is the first day of "real bleeding". Spotting belongs to the end of the previous cycle.
Ovulation occurs in all the books 14 days before the menstrual flow. Thus, in a 21 day cycle, ovulation occurs on average on day 7. The second half of the menstrual cycle may the 14 days in books, but it can be as short as 10 days and as long as 16 days in real life. Thus, in a 21 day cycle, ovulation could occur as early as day 5 (the uterine lining is probably not ready to be a good host) or as late as day 11.
Keywords: length of menstrual cycle.
