Letrozole for low progesterone

Hi All

I’ve been prescribed 5mg Letrozole to help with borderline low progesterone levels. I’ve been told I ovulate fine but having low progesterone could mean the lining of the womb won’t support a pregnancy (I am currently waiting for an embryo transfer).

I’m concerned as I have read it can cause super ovulation, I suffered through <a href="https://glowing.com/glow-fertility-program">IVF</a> with moderate over stimulated ovaries and was too sick for fresh transfer. Anyone else tried letrozole for low progesterone? I’m in the unexplained category for infertility. Also very worried about potential side effects.
