High risk - what does this mean for me?

Hey, I’ve just found out I’m pregnant, I am classed as high risk as last year I had an ectopic pregnancy & I also had treatment to have cervical cancer cells removed from my cervix so it’s now shorter. I have also recently found out I have CIN2 which means more cancerous cells have grown in my cervix 2/3rd deep. Ofcourse I can’t have treatment on that now because I’m pregnant. But I am wondering how they would treat me with high risk? Do I get regular scans/checks? If so how regular. Is there ways they can keep an eye on the cells in the cervix without interfering with the pregnancy?
