Bleeding for a week..?

Carole • 🌸💕
Last week I thought I was pregnant, but I either got a false positive or had a chemical pregnancy. The same day I got my 'BFP' my period showed up a day late. My periods have always lasted 4 days since I got them. This period was different...it lasted 7. Technically 4 with 3 days of heavy to medium spotting that was continuous. It never stopped for 7 days straight. 
Has this happened to anyone else? I was goin to call my doctor to get an appointment, but didn't want t seem like a worry-wart if it was just my cycle messing up... Any advice ladies? 
(P.S. The bleeding has stopped. It stopped yeaterday morning.)
