Pregnant and spotting

Nelly
Hi, ladies! I just found out yesterday morning that I'm pregnant. I think I'm just 3 weeks and 6 days along. I had a miscarriage last September and I'm scared that I'm going through it all over again. It happened right after 4 weeks. This morning I noticed some slight spotting. It's pink and doesn't seem to be getting heavier. Everything I've read says it's most likely implantation bleeding, but it just feels so similar to last year's miscarriage. Any of you experience this?
