I just had my first Depo shot mid February. For the last few days I’ve been spotting. Today I had a long string of discharge come out of me. It was about 3 inches long, and so thick that I felt it when it came out. I thought it was jsut a lot of blood, but it was actually it’s own independent string of discharge. Much of it was red, probably from the spotting, and part of it was somewhat cloudy.
