Help! What is this?

Stephane

I lost a baby a month ago at 4 weeks. I’m now pregnant with a new baby well.. my period is due the 18th, I’ve been having some on/off back pain, and cramps. I have been testing every day since I found out to see if the line gets darker because sadly I’m a Pee on a stick addict.. but just now when I wiped I saw this!! I’m freaking out...
