*trigger warning* possibly miscarrying

I just found out a couple of days ago that I’m pregnant. Today I am 17dpo and had my beta drawn, but my hcg is only 10. The dr. said I also have low progesterone, and she doesn’t think the pregnancy is viable. However, she just started me on progesterone suppositories in case it will help. Has anybody experienced this and gone on to have. A healthy pregnancy? I know there is a very high chance that I will lose it, but I want to hear from those with positive experiences so I can hold onto some kind of hope. I get another blood draw in two days.
