37w pregnant with my second child. I have SPD but since last night I have been in a lot of pain in my coxis, sharp pain in the bottom of my stomach when I stand and feel like my insides will fall out when I walk. Had to take codeine last night but was up in the night in pain. Currently still in bed 😐 Stomach muscles have been seperated since 15 weeks but have been coping really well. Assumed this was just SPD related but tmi I am quite wet. It's not pee! Odourless, colourless except for a tiny amount of white discharge. I've never gone in to labour or laboured so no idea what this is. No stomach cramps though. Suggestions? Ta
