Faint line..

took a test yesterday and got a faint line and today too. I'm supposed to be 4 1/2 weeks. but possibly ovulated later than I thought. anyone else have a very faint positive like this and go on to have normal pregnancy? I had a miscarriage July of last year. so I'm a little worried 😞. I need some words of encouragement. I'm gonna take another test in a couple days and see if it gets darker.
