Light flow after sex on depo

I've been on the depo shot for 9 months now and within the past month I've started bleeding after sex. Last time I had a light flow for 11 days after. I had sex again recently five days ago and I've had a light flow since. Has anyone else on the depo experienced this? When I looked it up I saw a lot of people experience the same but I'm still going to ask my doctor. Just wanted to see if y'all relate! Pls comment your depo-sex experiences I'm extremely curious
