Implantation bleeding? Help

Anna

Hi everyone, I found out I was pregnant with my second about a week and a half ago, I think I’m just over five weeks and today I’m lightly spotting when I wipe. It’s like pinkish. Could this be implantation bleeding or is it late for that? I’m freaking out I don’t remember this happening with my first. Please let me know if you have had this as well!!
