random bloody discharge throughout cycle

After having my daughter 6 months ago I've started to have bloody discharge a couple days after my period finishes, does anyone know what this is? Should I make a doctors appointment? Im having this discharge at random times throughout my cycle??? At the moment my cycle is around 31/32/33 days long. This has been happening since December 😩 I can't understand what it is or why it's happening if I've just had my period and I'm having bloody discharge throughout my cycle till my next period?
