Hooray and uh oh

Alyson
Had first appointment today, and baby looks great. Due date is spot on, heart rate 166. Everything is good, yea!!!
But.... the midwife noticed an abnormal spot on my cervix. She said it's an area where the cells are changing, but she wanted an OB to take a look. So now I'm going in again next week to see if it's ok or not. Trying to stay positive and not panic. My mom had breast cancer at an earlier age, so there is a history.... 
Anyone else been through something like this?
