Inplantation bleeding help?

Jamie

So I got off my bc and then a week later I go like a little period (which is normal but it didn’t last long) well on my apps it says I was ovulating on the 22nd and I had sex on days I was fertile & even after my ovulation. Well couple days later almost a week i have light blood but this time it’s more brown light brown & it’s light. Last time I knew it wasn’t ovulation bc it got worse later on but it hasn’t all day. I’m calling my doctor to see tomorrow but for rn I just need other people’s opinions. And here lately I have had lots of discharge idk if that is normal or not 🤔

Edit: I also have been cramping on and off and side pain and lots and lots of Lower back pain
