Why am I having such bad cramps?

(I suggest if you are not a woman, you don’t read this, it may gross you out. Just a suggestion)

For the past 3 days, I have had a TON of clear, odorless vaginal discharge, which I know is normal when you ovulate. However, I should be done ovulating by now and the discharge is SO much that I am soaking up 3 pads a day.It’s like I am leaking a TON of water. On top of that, I have severe abdominal cramps and some blood mixed in with the discharge (the blood is VERY LITTLE and just started today). My period is not expected for 10 more days. At first I thought maybe I’m pregnant and it’s an early miscarriage. Has this happened to anyone? I’m going to the hospital when my husband gets off of work.
