Period for 20 days

Mina

I’m 22 and very active. Have always had regular periods. I’ve been on BC pills for six years now and this month I had my period on the normal sugar pill week. A week later I got it again and have had since...it’s been 19 days I’ve been on my period now and the specialist doesn’t have appointments until the end of this month. I’m unsure what to do and if anyone has ever had this problem I could use some help.
