Previous MMC is making me nervous this time around!

I was pregnant for the first time this past summer but had a MMC at 6 weeks 2 days..found out at what should have been 8 weeks 2 days. I'm now pregnant again and currently around 6 weeks again and so nervous! This pregnancy has been completely different so far though. With the first pregnancy I had sore breasts from the very beginning and cramps consistently throughout the day. This time around my breasts aren't really sore but my nipples certainly are, I had light implantation bleeding early on, and I'm having strong food aversions, some smell aversions, and nausea on and off throughout the day, I also have very mild cramping occasionally but nothing like my first pregnancy. I'm praying that this is all a good sign and that our baby is healthy and growing. Anyone else dealing with anxiety or nerves because of a previous MC?
