Ok, Any Thoughts Would Be Welcome, As I Am Confused

Ok, any thoughts would be welcome, as I am confused and is desperate to know. This is my cycle. Since 20 Oct I notice a light pink on the toiletpaper. Usually early mornings and then it disappears and then I'll see it again in the afternoon. Today I had quite a big red spot on the toiletpaper, followed by light pink. It's the 3rd day now. I also have slight cramping. Period is only due 1 November. Isn't it too early for implantation and how long does implantation last. Haven't had it with my first pregnancy 8 years ago. Been TTC for 3 years now.
