So I am 22 with no children. Wanted to the skyla hopefully after 6 years I'll be ready. I know this is for 3 years. The procedure was okay the nurse said I took it well compared to others so I was hopeful. Ever since its been placed I've been having cramps & bleeding. She assured it was normal. Well now the blood is getting ticker & it's more dark red with alot of brown. That worries me. Why those colors?
