Progesterone suppositories

Hi ladies I’m 6 weeks 4 days today and have my first ultrasound on Monday morning and nervous... I had a missed miscarriage just this past December when I went for ultrasound at 9 weeks and baby measured at 8 weeks. This time they checked my HCG levels (I checked it four times) and blood work showed they doubled and doctor was very pleased... but I can’t help but have a ton of anxiety. Itshonestly all I have been thinking about and Monday can’t come soon enough. I’m praying so much everything is fine and I can breathe a sigh of relief. What scares me is I don’t have any pregnancy symptoms. Boobs aren’t sore, no nausea, I haven’t been peeing as much as I did in the beginning. Is any of this cause for concern? I do notice my boobs are bigger and my pants are tight. pregnancy after a miscarriage is really different. It’s been hard for me to be excited. I’m terrified and praying. Also, has anyone had any success with progesterone suppositories? My doc put me on 100 mg once a day Bc she said it was slightly low. So I’m praying this makes a huge difference!!!
