Anyone have any advice?

So this is my 3rd pregnancy. My first was lost in an early miscarriage at 5-6 weeks. So when I got pregnant the 2nd time, my doctor immediately had me come in for labs and I was put on progesterone suppositories until 14ish weeks. Unfortunately that doctor closed his practice so I had to go to a different doctor.. When I called to schedule my first appointment and told the lady my situation and all she said was that she would make a note in my file. I had to go in to sign a release for them to get my records from my old doctor and I'm still holding out hope they call after they see them. I don't want to just wait around and stress when I should already have had my levels checked. I'm 5 weeks 2 days and everything SEEMS okay so far but I didn't know anything was wrong my first pregnancy until I started spotting one evening and miscarried that night. I don't know what to do. Has anyone been through this? Anyone have any advice on what I should do? I'm so stressed about not knowing if my levels are okay or not. I just want to be able to enjoy my pregnancy and relax. I don't know why this new doctor wants to wait to do my labs until I'm 8 weeks 😔
