Heavy period with no cramps and continued spotting!!

Hello everyone, currently waiting for a bus so I can go get a hpt but I was wondering if anyone had similar experiences that led to a bfp?! Obviously I’m clutching at straws but here’s what’s gone down...

Normally have very painful periods, started af a week early than normal with no cramps. However there was a lot of blood, like a normal period and it even lasted a bit longer than I would expect (7 days instead of 4) I am still having brown tinged discharge 3 days later.

I don’t feel pregnant but feel like something is going on down there, I’m trying not to worry but I am freaking out actually.

Could I still get the bfp?
