I'm 36+6 and all day I've been having period cramping which gets more intense when I'm walking and I've also had occasional sharp cervical pain. I've had an increase in discharge, but it's think and off white ( maybe even a slight green/yellow tinge but no smell) and there was a slight pink colour when I just wiped. Baby was 3/5 engaged on Monday at my midwife appointment. Could this be the start of something? Should I go and get seen?
