Progesterone supplements

C

My doctor has me on progesterone supplements because my levels were low early on. At my 6 week ultrasound he said everything looks good (lining was thick) and that I probably didn’t need to keep taking the progesterone pills, but that I could until week 10 if I wanted. I’ll be out of pills a couple days before the 10 week mark, and they weren’t cheap through my insurance, so I’m wondering if I should buy a whole new bottle just for a couple pills to keep my mind at ease. If you were/are taking progesterone when were you advised to stop taking it?
