As of today, I am off the progesterone suppositories. I am still taking the PIO injections for another week. I am so nervous about not taking progesterone. I keep running to the bathroom to look for spotting. I'm carrying around 200mg of progesterone with me, so if I should start spotting, I will insert one right away.
So far, it looks like the placenta is doing its job. Fingers crossed.
