Infertility

Early menstrual cycle this month?

05/28/2008

Question:

I am trying to conceive, but this month my menstrual cycle came about 1 week early, on day 26. My cycle is ALWAYS between 30-32 days long, and has been for the past 2 years like clock work. I was wondering if my fertile time would still be as usual starting from this last period, even though it was earlier? Or would it be different? Would it be from when I would have had my 31 day cycle instead? Does it all matter?

Answer:

Women usually ovulate around 2 weeks before their expected period.  Therefore, if your periods occur every 31 days, you would ovulate around day 17, plus or minus 3 days.  Therefore, you would have intercourse every 2 days, from day 14 to day 20.

If you have been attempting conception for more than one year without success, an infertility evaluation would be indicated.  This would consist of a semen analysis in your husband, a blood test to see if you are ovulating, as well as a hysterosalpingogram (HSG) to see if your tubes are open.
