Implantation Bleeding

I won’t post a photo, but has anyone actually experienced implantation bleeding? If so what was it like? Color and symptoms and how long. I miscarried in October and we are trying for our rainbow baby. I am so nervous I started spotting yesterday morning light pink when I wipe and very little on a panty liner. It stopped and today the same except it’s really dark and just a tiny bit heavier but not enough to fill a liner. Cramps aren’t horrible. Could it be implantation bleeding? I’ve been having other pregnancy symptoms!
