Anyone taking 400 mg. Progesterone orally ttc

Jaimee Tuttle ttc baby#2💕

So my obgyn put me on oral Progesterone in December after testing with little to no Progesterone in my body after 4 weeks mc.

Last month they did blood work and came back still a little low😫 so they upped the levels to 400mg! Anyways, ever since I started the Progesterone back in December, I still have (not) had bfp!😭 It's been going on 8 almost 9 months now we've been (ttc)

Can progesterone be causing me to not get pregnant? Only time I had bfp was the first month we conceived and then lost shortly in November... I've spent so much 💰 on opk's and have tracked every little thing and am perfectly healthy with no health problems🤷🏼‍♀️🤦🏼‍♀️ anyone go through same thing and still ended up (bfp) after taking progesterone orally?
