Need some help/advice

I’m currently 8 days till AF is due to show up. I have creamy but not sticky CM and I have had a really light coloured blood show when I wipe, I’d say a small amount.

Is it possible that this would be implantation bleeding? I think I am 7DPO so too early to test.

Also, is it too early to have symptoms like sickness? Can anyone tell me how soon you’d expect to start having symptoms?

Please if you read this, please comment as so many posts go without a response xx
