Nerves

Does anybody else have these weird thoughts ? My first transvaginal ultrasound was at 7 wks and 3 days , ofcourse I have to wait 4 weeks for my next which is next weds and I'll be 11 weeks and 4 days , my last ultrasound I saw and heard my baby's strong heartbeat and after reading sad story's I'm just so nervous to see and hear what may or may not be there at my next ultrasound , mind you no bleeding or anything crazy it's just random scary thoughts that I have
