Hi I was literally about to post this same question, I've not had heartburn really until this eve and feeling a bit sick, I'm 38+4 bit of mild cramping but nothing else, no idea of it means anything
I was sick the same evening my waters broke. Had a massive wave of nauseous too. Don’t rule anything out. Midwife’s on triage number didn’t believe me with my waters because if the colour of it but soon as I got seen they agreed. Prior to waters breaking my body was definitely trying to clear itself out of poop as I went several times a day for the last few days (wasn’t diarrhoea).
Sign of ongoing pregnancy more so than labour but never say never 🤷🏻♀️
