Faint line

I bought this test from the dollar store today and got a faint line!! I thought my mind was playing tricks on me so I went and bought a cheap test in case it was negative. Glow says AF is due Monday while another app I use says it was due yesterday. My husband and I have been trying for 3 months. We had miscarried at 9 weeks in February. So excited and not trying to get my hopes up for fear if miscarriage again. ​
