So I've had bumps and itchiness that started on my bellybutton around 13-14 weeks. Im 16 now and it has expanded to a small spot on my elbow and the crease where my thigh meets my hip. Now I think a new patch is starting up behind my knee. I read about puppp, but when it first started my friend (who is also pregnant) told me that her husband had scabies. I haven't come into any contact with him but I was around her and her son a lot and Im worried that maybe I might have picked that up. Anyone had either one of these and can help me out with the differences??
