Your short plan for this week

Do now

Notice the trigger for pelvic or back pain—turning in bed, stairs, standing, lifting—and ask early about tailored physiotherapy or movement advice.

Coming up

Ask how to access pelvic-health support in your system and whether a referral is needed.

Pause and ask

Do not push through sharp pelvic pain in the hope that more exercise will automatically fix it.

Contact your doctor or maternity team promptly
