delayed ovulation and miscarriage?

[blue76]

hi,

I've always had 28-29 day cycle with ovulation around day 14. Since my 2 miscarriages, the last one was 3 months ago, I'm having longer cycles with ovulation  at day 20-21 (confirmed with fertility monitor and temperature) and a luteal phase of 12 days. With my last miscarriage I ovulated on day 20 and had a missed abortion. I am reading about a link between delayed ovulation and miscarriage. What is your opinion and the general opinion among your colleagues? To me the explanation about old eggs seems reasonable. I'm just wondering what to do, I'm scared to conceive again while having a late ovulation. Is there medication to get my ovulation back on track?
thanks

Hello,

I don't know your age but that would be informative as you are asking about confounding issues.  The two confounders are that with increasing age miscarriage rates increase (most commonly due to an increase in chromosomal abnormalities secondary to aging oocytes), and with increasing age the menstrual cycle can begin to vary in length by 7 days or more.  So it is not necessarily the change in cycle length (or a change in the luteal phase) that is the cause of a miscarriage, but rather the fact egg quality continues to decline with age.

Medication will not get your ovulation on track, but you may benefit from assisted reproduction with or without a donor egg if ovarian reserve (that is to say egg age) is a major concern.

Best regards,

Dr. Downing
