Progesterone - Long story- please read and help!

So hubby and I have been ttc #2 for about 10 months. I have been going to a weight loss Dr for 2 months now and have lost some weight but when they took my bloodwork they also checked hormones and my progesterone was 0.3 (but it was 2 days after my period so idk if that affects it or not) and I was told that was super low as a “normal” range can go up to 50 for someone my age. So I started on 25 mcg of progesterone in pill form and 25 of the cream and then I was told to double up on day 15-2days before expected period. Now the Drs know we’ve been ttc, but I had the mentality of while I’m trying to lose it’s ok if I don’t get pregnant right now, I need to focus on my health so this progesterone isn’t necessarily to help ttc; it’s more for overall feeling better and with making my hormones where they need to be in general. I feel as though it has helped me ovulate on time (usually don’t ovulate til day 17/18 and this month it was day 15) and I’m hoping to test this weekend just to see if I AM pregnant.

My questions are:

1. If I stop the progesterone and I AM pregnant, will it hurt the pregnancy?

2. If I don’t stop the progesterone in time before I am supposed to start my period will it mess up my next cycle?

Anybody taken progesterone and it helped to get pregnant? Any advice at all here?

Thanks for reading this long post!🙈
