Spotting?

Today i noticed super light pink spotting with alot of discharge I'm about 7 wks. First Dr apt is in 4 days. Is this normal should I worry? I have to work tonight almost a 9 hr shift. I haven't even had a confirmation appointment yet either, because when I was about 4wks or so planned parenthood told me my faint positive on 3 of their tests were inconclusive. And wasn't pregnant. Jokes on them because the following day I had a clean positive on a first response and a clear blue digital. And continue to get strong positives.
