Thyroid and pregnancy....anybody else?

So. I'm almost 36. I do not have a thyroid due to thyroid cancer almost 2 yrs ago.

I've had 3 early losses before this pregnancy.

I know my labs/levels are not conducive to a healthy pregnancy and yet me/baby are still holding on.

I started taking progesterone as soon as I found out I was pregnant because we discovered my losses are due to my progesterone bottoming out.

Plus I'm endometriosis, polycystic ovarian syndrome, and I'm prone to pre eclampsia.

Anybody else have similar issues?
