Bleeding

I'm 5 weeks 1 day according to the app.  I spotted very little brown discharge Saturday and nothing yesterday and now I'm having pink bloody discharge and it's really freaking me out. I have a 5 year old and don't remember this.  I'm having some back pain, but that's kind of normal for me, no real cramps though.  What do you ladies think i should do?  I don't see my dr until April 1st.  They said they don't make spots until at least 8 weeks.   Soo anxious.  I wish this bleeding would stop.  It's not a ton, but I would say more than just spotting.  Please tell me if anyone has experienced this.  Thanks.
