TW: pregnancy/loss

In September of 2023 we suffered a MMC.

We found out we were expecting our rainbow in April and went for our scan today just a gestational sac measuring 5 weeks 6 days. We were thinking we were 7 weeks. Now we have to go back in a week to see if anything changes. Has anyone been through this and can share their experiences? Also how to advocate from here. I will add I have a 3 year old that I got pregnant with no problem and am currently on progesterone suppositories due to low progesterone and history of loss. We also did HCG draws all doubled within 48-72 hours.
