Possibly pregnant.... low progesteone


Edited to add: TW mention of Miscarriage

My period is 10 days late. I took several pregnancy tests and they are coming back with very very faint positives. I had a miscarriage last year and I was told when I found out I was pregnant that my progesterone was low. I was given a prescription for progesterone but still lost the baby. Then when my periods weren’t cycling correctly they gave me another script to help them along.

Since I am getting very faint positives should I go ahead and start the progesterone again to help the baby along (I have some pills left over)? Does anyone have any tips or advice on taking progesterone while pregnant? And if my some chance I’m not pregnant will it harm me to take it? I’m so scared and nervous being possibly pregnant again. All the emotions from the miscarriage are flooding back to me. I just don’t know if I can do that again. Anyone have any advice?

Side note: I do have a doctors appointment scheduled but they can’t see me until next week and I am very impatient.
