Cramps and nausea help

So I had a MC last December so Im kind of scared. They say it's rare for what happened to me to happen again twice

Anyway, things seem different this time but I'm crampy. Usually if I sit down or drink water the cramping stops, it's not heavy or all the time, I really wasn't crampy the last time, could this be good or is it bad? ? Also I was feeling a bit nauseous at first but last night I got so bad I threw up. This am I felt like I was going to Again and most of the day I've had waves of huge nausea.

Does this all seem ok or should I be concerned?
