When to call your provider or get help

MedlinePlus says to call your provider in the third trimester for:[13]

  • bleeding, or discharge that smells bad;[13]
  • fever, chills, or pain when you urinate;[13]
  • headaches or changes in vision;[13]
  • the water breaking, or regular painful contractions;[13]
  • the baby moving less;[13]
  • a lot of swelling, chest pain or trouble breathing.[13]

The NHS says you should still feel the baby move at the same rate until you give birth, and to contact your midwife or hospital as soon as possible if the pattern changes or the baby stops moving.[3]
