Clomid and a "21day" progesterone

Hi all! I have been on clomid for 4 or 5 cycles. 2 months ago I never got a positive opk so I never went for a progesterone test. Last month on 50 mg clomid, never really got a true positive opk, but MD used the date with the "darkest line" and had me base my 21 day lab off that... I had a very low progesterone level, like 2.... so MD bumped me up to 100mg this month. Well just got my results and I had a result of 29!!!

What experiences have you lovely ladies had and what kind of progesterone levels ended in a BFP!?
