ultrasound

Need advice. My dr made me come in for my first appt at 6 weeks instead of 8 due to a history of MC. So I was too early for a ultrasound. My next appt isn't u till February and I will be 13 weeks. I haven't got to see my baby yet and I'll be 8 weeks next week. I asked my FB friends if there was a place I could go get one at and everyone was so negative and told me not to do it. I want to see my baby but I also don't want to hurt it in anyway. What's yalls opinion? What should I do? NO JUDGING. FTM.
