Implantation bleeding?

Kj
So today I started spotting on cd 34...still no actual period...sorry if this this tmi but I have the brown "leftover" blood I normally get at the end of a period...but I've never had spotting any other time...before my mc I was on a 29day cycle and it hasn't been close to that for a few cycles. I'm hoping for implantation bleeding and my rainbow baby! Opinions please
