A member asked:
21day progesterone test shows no ovulation. bbt & pos opk suggest i did. temp dip on test day but shot back up. can fluctuations cause false negative?

2 possibilities: BBT and OPK only work sometimes and often they are wrong. the blood test is much more accurate. so either you did not ovulate, or your ovulation was a very poor quality and your progesterone level dropped down very quickly. either way it is not a good sign

Letrozole Cycle CD 3 through 7 5 mg OPK turned positive on CD 11 evening (early for me even on a letrozole cycle. I usually ovulate on CD14.) My lab orders for progesterone were for CD22 my labs came back @ 8.2 Is this low for a letrozole cycle?
My day 17 progesterone level came as 8 ng/ml and LH is 1.6 miU/ml. Opk turned positive on CD13. Did I ovulate this cycle?
Are opks and blood progesterone tests enough to 100% confirm ovulation on clomid (clomiphene)? I'm concerned my doc isn't monitoring via ultrasound. Should she be?
My doctor instructed me to take progesterone suppository (400mg) 36 hours post positive opk. Mistakingly, I took it at 24 hours. Usual ovulation time is 24 hours post positive opk. Will this hinder ovulation? What should I do next?
OPK should I take 200mg or wait 2 days to take progesterone? Will progesterone hurt/stop ovulation if taken the first day of +opk or can it help.
