6 week scan: Comparing this pregnancy to my last pregnancy that ended in MC

I'm 36 and had a miscarriage when I was 32. We decided to try again in 2024. Here's a short comparison between this and my last pregnancy at 6 weeks. Compared to my last pregnancy, at 6 weeks I'm a lot more nauseous and have not had any bleeding. The last time I miscarried, i had bleeding and the fetus had a slow heart beat and my hcg was also low. I ended up mc at 10 weeks and had D&C at 11 weeks as it didn't come out. This time around, the fetus seems normal with Heartbeat at 130. Fetus at 3.15mm. I'm exactly 6 weeks from the 1st day of last period. And the baby is also 6 weeks old based on scan. However I think everyone is different and some may have a different gestational age on the scanning. Hoping everything goes well along with anyone else who had a miscarriage before :) and who is anxious about being older.
