Pregnancy test!

In the past four months I have had a 10 week missed miscarriage that ended in a d&c and then two months later I found out I was pregnant with an ectopic pregnancy in my left tube and had to have the pregnancy and my tube removed. Now four weeks after my ectopic surgery I have taken three pregnancy tests and all of them have a very faint line, but I cannot tell if there is any color to them. We were not even trying this month and since I haven’t had a period since my surgery I have no idea what cycle day I would be on or anything!
