Don't feel pregnant anymore whatsoever?!

Ugh. I am 1 day away from being 12 weeks. I do know that symptoms will usually subside around this time, but I started feeling 80% better at 10 weeks and then even more normal during week 11 except a few headaches. My symptoms have been mild from the start but my nausea and food aversions did get pretty bad from weeks 5-8 before they started to taper off. Boobs also were very tender during those 3 weeks. Today I woke up feeling basically 100% normal. My appetite is back and I don't feel the breast tenderness, nausea, ligament pain or bloating I was feeling before. No belly at all from what I can tell. I'm not even getting up in the night to pee like I was before. We saw a good looking little bean with a good heartbeat at 9 weeks but I can't help but worry. I read so many stories about MMC and I have such bad anxiety that is happening to me. After 3 years trying and one loss already I don't know what I would do. Has anyone else been through this but had a healthy baby? So nervous for my doctors appt on Friday...
