Make rest and low-risk stress relief part of the schedule.

Call your care team

Call for bleeding, leaking fluid, regular painful contractions, fever, high blood pressure readings, or movement changes.
Seek urgent help for severe headache with vision changes, sudden swelling, chest pain, fainting, or trouble breathing.
