Long period cycle affect fertility?

Hi Dr. Brown,

My husband and I (ages 34 and 30 respectively) have been trying to conceive for 4 months now.

My period cycle averages 31-35 days. I was wondering which day we should try conceiving? At first we had unprotected intercourse a few days before ovulation but I've been reading that it should be earlier. Would you suggest Day 12 til the day after my ovulation date?

Also does my longer than average cycle affect fertility? I've been really hoping to conceive and want to take a proactive approach and get some fertility workup. My husband has been a smoker since high school and quit last year. I'm concerned about his sperm quality and my long cycles.

Please advise. I appreciate you reading and thanks in advance.

First of all, congratulations to your husband for quitting smoking after so long!
That is not easy to do, but it is a wonderful gift to your baby to be!
His sperm count should have improved already, as it takes about 3 months to "manufacture" sperm.  

Regarding your long cycles, ovulation occurs exactly 14 days before the period starts.
So, for a 31 day cycle, subtract 14 and the ovulation day is 17.  Cycles that are longer than 31 days are not considered normal.  So, it may be that you are not ovulating every month.  One way to find out would be to try ovulation predictor kits--they are available at most drug stores.

If your ovulation predictor kits are not consistently turning positive, you may wish to schedule a visit to your doctor.  If you were my patient, I would do a progesterone level initially to determine whether you are ovulating--and then work from there.

Hope this helps!
