I've been frequently opening my bowels (soft not diarrhoea) for the past few days now (this is not usual for me, I am constipated even when not pregnant)...I have had back ache and period like cramping on and off mainly since yesterday evening and believe I am losing small amounts of my mucus plug this afternoon (clear, snot like)..I am 33 weeks pregnant due to be induced at 37 weeks due to baby being a lot smaller than he should be! Is this the start of preterm labour or does this mean nothing??? THANK YOU
