Goodness, sorry coolstar, I should have read your sig instead of asking silly questions! I think if the temp shift is there and your LP is consistent then you're definitely ovulating, in which case wow yes, you have mega low progesterone!
Will your consultant give you a HCG shot as extra oomph at ovulation, or progesterone suppositories? Def sounds like you need a bit of extra help.... and a doc that believes you ovulate.
I've taken B50 for two months and have seen an improvement in my spotting, but not hugely so. Upping to B100 next cycle so will see then if there's further improvement. I don't think it will ever provide as much help as basic progesterone suppositories/injections would do.
