Worried, help appreciated❤️

I had a miscarriage back in June and am currently at the farthest I’ve ever made it before! I’m 8 weeks and 2 days. Yesterday and today I almost didn’t feel pregnant. My boobs and nausea were slight but I didn’t feel bloat at all. Now, late as heck, 11:50 I have all the uterus pressure in the world. Anyone ever experience this before? I’m scared to miscarry again. I don’t have my first appointment until the 5th. By then I should be around 9w 5d. I’m so nervous.
