Why am I only spotting

A

Past three months have been horrible I want to have a full blown period and I only spot for three days with no flow I don’t have clots no crimson colored blood just light pink in color. Yesterday I wiped and saw blood on my tissue and thought that my period came a day early. I’m not pregnant all my test are negative. Last month my Ob had put me on progesterone to help me start a normal period I took them at the same time everyday except once for 10 days and still I didn’t have a full blown period I spotted for three days. I made an appointment but can’t be seen til the 29th. I don’t want to hear that it’s normal but it’s not normal Iv always bled not just spotted so I know this is not normal for me. I been off depo for 6 months I wasn’t even on it very long 7 months. I got my first shot in July of last year.
