First scan tomorrow! Nervous 👶🏻🐻💙

Hey all, I have my first scan today (08/02/18)

From going off my last period I am 12 weeks and six days but I haven't had a scan yet so I'm unsure.

Basically when I conceived I was on medication to help my pain as I suffer from chronic fatigue and also nerve disease. I'm only 23 so still young and this is my first pregnancy. I'm absolutely terrified about my scan. I just want to know that baby is okay and I haven't done anything wrong. I literally can't wait to see them on the screen me and my partner are both so so excited but i'm even more nervous

Did anyone else feel like this and was everything okay
