Short luteal phase = definite miscarriage? If so, when? - Page 2

  Well, the OP would have her answer by now!

I would like to introduce a new concept here- a short luteal phase is more likely to indicate a lower quality egg ( which may be more likely to have genetic errors as well as cytoplasmic errors).

Thus, a pregnancy resulting in such a cycle, even if implantation occurs successfully, may be more at risk for miscarriage.

This is not a hard and fast rule, but seems more plausible.

I've had two pregnancy losses with conceptions occurring in cycles where my lp would be a short 11 day deal.

My luteal phase has increased after I took vitamin D3.

More information is on my blog.

progesterone would be my first guess as to a later miscarriage.A short LP (too short) will not supply enough progesterone for implantation..You can not know what your LP was until your next AF comes.Some people are lucky to have a textbook cycle (same length each month) and o the same time every month.Most woman do not have that upper hand. in may my cycle was 25 days with an LP of 9.In june,my cycle was 27 days with an LP of 11. july was 28 days with an LP of 13. august was 28 days with an LP 12.Fertility Friend is a great tool.However,if your cycles differ often(i dont mean irregular)..any tool can be confusing.

Just wanted to add my two cents...

For as long as I've been charting (about three years), I've always had a luteal phase around seven days. Sometimes it varies (six or eight days), but that is very rare. My son was conceived the second cycle we tried... The preceding two months, my luteal phase was only seven days.

We've been TTC again and I've tried B-50 complex and B-100 complex, and my luteal phase has remained at seven days. I had a chemical pregnancy last month. 

I've done quite a bit of reading about short luteal phases, and my understanding is that many reproductive endocrinologists are now calling the "luteal phase defect" a myth. Anecdotally, I've also seen stories of quite a few women who have easily conceived with a short luteal phase. 

I just wanted to throw that out there so women don't become disheartened by having a short luteal phase. FWIW, my son was conceived quite easily with a seven-day LP. 

Thanks!
