5 weeks 6 days 96000 hcg levels? Should I be concerned it is so high?

I had some brown spotting with lots of cramping so I went into my doctor. They said they want me to come in about every ten days for awhile. My gestational sac grew 2mm a day from when I first went in until now. I'm definitely 5 weeks 6 days, but now my pants barely button. I have had horrible morning sickness and lost a few pounds though. Has anyone else had this? I've been reading about molar pregnancies, do they still have yolk sacs and everything? Or am I just googling too much about what this could mean....
UPDATE: my doctor doubts it molar due to how the baby is growing, and said my numbers would be a lot higher if it was. He wants to check for multiple heartbeats next Friday!
