I stopped and only took those meds that were prescribed.

OP here. Yes, it supposedly supports egg quality but since it also helps cells with energy and division, I figured this week may be the one to use it! (I am four days post transfer)

I continued taking it until about 9weeks (post-transfer, confirmation of pregnancy, up to 1st regular OB/GY visit).
Then, I stopped.

Just regular prenatal vitamin and extra calcium for me.

After transfer, just the meds that my doctor prescribed + my prenatal. If you want to continue taking it, I'd clear it with your MD first. But isn't the idea of CoQ10 to improve egg production and quality?

Nope

I stopped the day before.
