Implantation bleeding?

With my last pregnancy I had bright pink spotting, I only noticed it one day when I went to the bathroom and wiped, that was it. No blood or anything... But I have heard from other women they had pink spotting and some red very small amount of bleeding going on and even brown in color. Either way I agree with you this is strange. You know your self and you're cycle and if this is different than usually I would say it's worth checking into. Maybe in a week or so take a test and see what it says. Hope this helps...
