Low progesterone

E.
I found out days before conceiving that I had low progesterone.  Midwives weren't concerned but said it could impact my ability to carry a pregnancy.  Once I got my BFP, they did additional bloodwork and progesterone was 2.88. I'm 5w1d and starting progesterone 200mg today to take throughout the first trimester.  This is my first pregnancy.  Anyone have a similar experience or words of encouragement?
