Implantation bleeding or period coming?

Hello everyone, I’m going out of my mind here has anyone experienced anything like this. I’m not sure what DPO I am but I’m due on my period in 2 days (3rd Jan).

For the last 5-7 days I’ve had cramping and last 2 days I’ve had brown/light pink discharge. I’ve never spotted before so this is unusual. I had what I thought was 2 BFP but these are evaps (I think as they showed up after an hour). I took

Two more tests today and they are BFN. I’ve also had sore boobs for the last week or so but today they are not as sore hardly painful.

I did think this was implantation bleeding but with my boobs not hurting as much I’m now thinking my period is coming. But I’ve heard boobs can hurt on some days more then others while in the early stages. We are TTC and I don’t take ovulation tests so I’m not sure when I ovulated but I BD around the time I thought I was ovulating and more :).

Anyone had anything like this?
