Sharp pain?

Okay ladies.. so I started massively bleeding and clotting yesterday. My period came two weeks early but I'm thinking due to stopping the nuvaring. I had severe cramps. Now today, I woke up and stood up and got a pain so bad it doubled me over and I couldn't move, speak, or breathe. It had me sweating and shaking because it was so bad. But I wasn't bleeding this morning before this. So I went to the bathroom and with this horrible agonizing pain came a very small bowel movement and with that, blood starting POURING out again. Is this normal..? Sorry for the tmi.
