Lots Of Clear Fluid Filling Up Tampon And Leaking Onto

Lots of clear fluid filling up tampon and leaking onto underware. With little blood on tampon. I take out tampon and it's half filled with clear fluid and the other has blood. I reach to touch the cervix and i get red blood. This is also my first day of cycle. I have also been trying to concieve. I also feel the urge to pee. And I was thinking maybe it was. But it's not urine.
