Possibly pregnant

My period was 4 days late and today I took two pregnancy test and they both were positive. Normally I would be thrilled about this but I’m sorta freaking out. For the last 11 days I have had on and off light spotting. It seems that’s not a normal early pregnancy symptom and I thought spotting was only suppose to last a few days. On top that I haven’t had any other pregnancy symptoms. Has anyone else experienced this before? I’m just really worried and want to enjoy this pregnancy if it could be true but I don’t want to get too excited if it sounds like a miscarriage.
