I am pretty sure that i never had this when I ovulated on my own - I never spotted or cramped before AF, just on the first day when AF showed. On the one clomid cycle where I did not get pg, i was on progesterone (not for lpd but because my progesterone dipped after i got pg) and it took 4 days after stopping the progesterone to get AF (17 dpo). And i was only taking 1 endometrin a day...
with the last femara cycle, I took 2 endometrin and 2 prometrium a day, but got crampy by 11dpo and had a little spotting on 12 dpo (I didn't take 2 doses of the progesterone on cd 11 because I tested bfn, but later thought better of it and took it again). AF showed up 14dpo even though I had only been off progesterone for about 12-24 hours.
This month again at 11dpo I was pretty crampy and had a backache (even though I am taking 2 endometrin and 2 prometrium a day) - both the cramps and backache come and go....is it possible to have lpd on femara but not clomid or on your own?
Also - do you only have luteal phase defect if you start bleeding early (11 dpo or earlier) or is early cramping/backache at 11 dpo also considered lpd even if you don't bleed?
