Nuvaring none sense

Amber
I just stopped the nuvaring last Friday...I was having pregnancy symptoms on it but kept testing negative....Now I'm experiencing bad stomach pain, frequent urination, leaking urine, moodiness etc. I started bleeding, like a period type, 3 days ago but it doesn't look quite like a period. Any ideas of what's going on? Could it be a miscarriage? Please help. I'm really worried.
