have my water finally gone??

Ja
i am now 41 weeks 1 day I have been in hospital twice first time it was my mucus plug I lost and the second time I thought my waters may have gone as I was discharging watery stuff and was told it was still bits of my plug still, this was 2 days ago. Now I've woken and I am soaked down there so I got up to go toilet and I had like water with blood streaks in my underwear so I wiped and light pink water is coming from me this all happened at 2:45am it's now 03:43 is this my waters this time as I am getting period like pains coming and going ans my stomach is tightening, I don't fancy another trip to the hospital to be told it's my plug still as it makes me feel quite stupid even though this is my first baby so everything is all new to me x
