I am 39 weeks and iv been loosing some clear mucus for over a week when I go to the toilet it’s in the toilet water. Last night I had some spotting it was just pink. I went to sleep and woke up this morning having mild contractions, they seam a bit erratic and all over the place but some are quite strong and I have to breath through them, I feel it starting in my lower back and wrap around my tummy rather than just my tummy. Could labour be starting ?
