Should I be concerned ?

I started testing this past week, my cycle was due yesterday 2/1. Wednesday I took a First Response test it was negative, Friday I decided to test again it was positive. I’ve tested daily since and my line isn’t getting any darker however I have tested using a clearblue digital and it said Pregnant. Last year I experienced a chemical in March, Ectopic in August where I lost my left tube and another ectopic 10/29 which was treated with the shot. I’m super nervous, I never have any pain, nor do I ever experience any pregnancy symptoms.
