6 weeks 5 days no symptoms

I'm sort of freaking out. I'm 6 weeks 5 days today and I have no real symptoms. My boobs have gone in and out of lightly hurting and no other symptoms. However, I am very gassy and a bit constipated. Maybe a little more tired than usual-hard to tell given the heat the past couple of days. I can't help to think my pregnancy is not developing.

For context... last year I had a MMC at 9 weeks baby stopped developing at 6 weeks. Two months ago I had a chemical pregnancy. And now I'm pregnant again, just as we had our IVF appointment. We did all the testing mostly all normal except for fibroids but according to the doctor they are unlikely to cause problems as they are on the outside of the uterus. They didn't do any karyotype testing it seems to have been an oversight on that.

I have my midwife appointment today but they don't do scans there so I know I won't get any assurance today. I'm honestly going crazy here. Has anyone had no symptoms this far along and everything been okay? During my MMC I did have mild symptoms that remained until my D&C.
