Progesterone

Looking for any stories of success after being put on progesterone suppository. Today I found out my hcg level was doubling but my progesterone had dropped to 9.4. We did an ultrasound and I’m measuring great. No cramps and no spotting. Having all the pregnancy symptoms. They put me on progesterone. Has anyone at 5 weeks had success that didn’t end up in a miscarriage? I’m trying so hard to be realistic but also hopeful.
