Question on spotting!

So a couple of nights ago I had the smallest amount of spotting (pink) on the toilet tissue. I’m only just at 5weeks.

I’m sure that this is too late to be implantation bleeding or am I wrong?

I’ve had nothing since so not told anyone- especially not my husband as he’s been more nervous than me during the pregnancy as we miscarried earlier this year.

** Update **

Had an early scan today- there is a pregnancy sac visible on the scan which is nice and round/normal looking. Too early to see a heart beat. Got another scan in a few weeks, fingers crossed! :)
