So I had my positive test almost 2 weeks ago. The day after my positive I started bleeding and bled for a few days. I thought maybe it was a chemical but turns out it wasn’t. They had me come in when the bleeding stopped and drew beta hcg over the course of a week they were

May 16 was 17.5

May 20 was 60.7

May 23 was 113.3

On May 23 they also checked my progesterone which came back at 4.4 which I know is low but my doctor said he doesn’t want to start me on supplements at this time and he wants to draw more levels next week. My question is without progesterone supplements will I for sure miscarry with a level that low? I just don’t understand why he won’t give me any supplements. I just lost my baby girl and had a D&E on April 9th I was 13 weeks 5 days with her but they never checked any levels. And now I’m pregnant again without ever having a period in between, could that cause my low progesterone because it’s so close to my last pregnancy?
