Im 39+1 and been having constant period pain and lower back ache for 5 days! I've been taking paracetamol which doesn't seem to help much, I also have sharp stabbing pains right down low! I think I might have lost my mucus plug this morning...it was clear but thick and snotty looking! I'm having tightenings in my tummy which are regular but not Painful...could I be going into labour soon?Help!
