Help :)

Okay so my last period was may 17 - 21. Supposedly my ovulation day was the 5th of june, however, on the 8th of june i started bleeding and ive been bleeding ever since. Light at first, then last night it suddenly got darker and it had 1 big clot. Today, i felt something come out, thinking it was blood, but when i checked it was clear. It wasnt even tinted pink. It looked like i mightve peed, but it wasnt pee. So i guess im just looking for insight on what the clear watery liquid may have been. I wasnt cramping at all until last night, and my back hurts pretty bad right now.
