Am I in an early sign of labour?

In the morning, I woke up with a sharp pain at groin area (contraction?). When I was walking to toilet, I felt like an amount of water flowing. I thought it was my urine, got a shock when my urine color a bit reddish.. I tried to pee again abt 15 mins later and got blood discharge with mucus, and as I got up, I felt got water coming out again.. I put on a pad and within an hour, not fully wet, but, got a bit brown discharge.. Is this considered early sign of labour? How long does it usually last? Btw, I also having cramp like menstrual cramps and I can feel baby is moving also.
