LP too short?


Hi all,

I have been TTC for 8 months now, on Friday (day 21) i had a blood test which will test my LH, FSH and progesterone levels.

For the past few months i have been wondering whether my LP is to short.This month i O'd on day 15/16 and today im spotting, which is day 24 (8/9dpo). I know this is not implantation and i know i can expect to start af in the next few days.

My questions are:

1)Does this spotting mean my LP is too short-if im spotting now, will my egg have any time to implant! once iv started spotting, can my egg still impant if it is fertilised?
2)Will the blood test i had on day 21 show whether i have a LPD by the progesterone levels?

Anyone know or experienced this in the past?

Thanks xx

Hi babyblog,

I'm not sure about your first question. It would probably depend on if the spotting was fresh red coloured or old brown blood.

Fortunately, the 21 day blood test will show if progesterone levels are too low. I did a bit of research after my last cycle resulted in an 8 day LP and found that the 21 day bloods are used to confirm LPD.

Hope your doc can give you answers soon.

Thanks Amerikiwi, it is brown blood so i guess its old blood not new, i guess im wondering whether if this is the start of af an egg couldn't stick even if it wanted to!
Thanks for letting me know about the day 21 test, im looking forward to getting my results asap xx

Make sure your doctor knows that you didn't Ov until CD15/16, as the CD21 bkood tests are timed that way as they presume (!!!) that everyone Ov's on CD14, and therepfre aren't CD21 tests at all....they are tests that measure your progesterone 7 days after Ov....so yes yours will show a tad low, being a tad early.

8 or 9 day LP.....hmmm, well theoreticaly its shorter than ideal, Normal is considered 14 days, however the medical institute as a whole doesn't even bat and eyelid if it is 12 days. Theoretically its considered short at under 10....however, many docs now are looking at individual cases before commenting as each body preduces hormones at its own rate, so whilst 10 days may not be good for one person, 8 may be fine for the next.

I personally have carried two babies, one to term, and one to 10 weeks (where I had a missed miscarriage - so my LP played NO part in that whatsoever) with an LP of only 8 days, and I'm certaibnly not alone.

I think you are doing the right thing by getting tested though.
