Supplemental progesterone

Has anyone here had to use supplemental progesterone during pregnancy without bleeding? I am 4 weeks 6 days today and was prescribed progesterone suppositories. I had my progesterone checked because I was concerned about my bbt not staying elevated enough. I did experience implantation bleeding at 10DPO, but no bleeding since. My progesterone was only slightly low for pregnancy so we are supplementing. I’m just wondering if anyone here has had to do this and had a good outcome.
