Is this a miscarriage?☹️

Caitlin

So my fertile window was the week of October 27. I had what I thought might have been IB on November 5-8. Very light, pink, only when I wiped. Never progressed. Got my BFP (on a few different tests) just two days ago, so November 13.

Yesterday evening, I noticed more spotting. Again very light, mostly brown some pink, only when I wipe. Very light cramping on and off. This has continued all day today as well. Could THIS be the implantation bleeding I thought I had the week after conception? And if it is, what was THAT bleeding? My period would be due today or tomorrow.

Or is this as I fear☹️ Just looking for women with a similar experience
