Afraid of miscarriage

Ka

So I have a history of miscarriage and ectopic. One of witch left me in the hospital for a week. We are so scared it’s going to happen again. My doctor told me everything looked normal so we were going to go on as if it was. But to take test every couple days and as long as the line gets darker I should be good no need to worry. Does my lines look like they are getting darker?
