Okay, I should probably spend a few more minutes googling this, but figured you ladies might know faster. But will my progesterone supplements (prometrium oral pills) make my LP longer? I know they can cause more symptoms and higher temps, but will my AF be delayed too?
After 2 m/cs, dx October 2008 with hetero factor v leiden & mthfr & low progesterone; third time was the charm - BFP 3/19/09 on first cycle of clomid.

Re: Progesterone Supp Question
Oh, that's interesting that it might have contributed to an earlier O the next cycle. I hope that happens for me.
Thanks ladies. My temps are still up and they normally drop today and AF would normally be due tomorrow. I guess my temps staying up is to be expected a few days extra though. Oh well.
progesterone will lengthen your lp - that's one of the reasons to take it
longer lp = later due date for period
prog also causes false high temps
Oh, I hope so! I'm not too optimistic though b/c I had a BFN yesterday and no real strong symptoms like with my last two bfps.
