Help - spotting problems

I'm on this new birth control called "Lolo" and I missed one of my pills last week. I started getting what I thought was my period this past Saturday (days after missed the one pill), but the bleeding still hasn't gone away; it's more like spotting than an actual period but it hasn't stopped in 5 days, and I'm still continuing taking the pills as I normally should. What should I do? Should I stop taking the pills and hope the spotting goes away, go to my doctor, or go to the hospital?!
