Help please!

Last July I had a miscarriage. It was our first pregnancy...the baby stopped growing at six weeks. I am currently 6 weeks pregnant with our rainbow baby, but today I'm having pink spotting when I wipe. I'm really worried so I had my nurse call me and she didn't really ease my worries...the spotting is super light pink and only when I wipe. Has anyone had this happen to them before? Was your baby okay?
