Did I have a miscarriage ?

I found out I was pregnant 2 weeks ago and on Thursday at 3 I started spotting and it went on until 11pm on Friday. I didn’t have any clots and it was either light pink or bright red but it wasn’t heavy bleeding. But I don’t feel pregnant , I don’t really have any cravings and I’m not nauseous but my breast is still a little sore. I took a pregnancy test 30 minutes ago but to me it doesn’t look dark enough. Even though it was just spotting for that time could I have had an early miscarriage? Since I stopped bleeding I have been cramping a but it hasn’t been bad and i’ve had on and off back pain.

Does the line look too light for me to be 4 or 5 weeks pregnant.
