Your short plan for this week

Do now

Test small comfort changes: a pillow between the knees, support behind the back, shorter standing periods or a footrest at work.

Coming up

Raise sleep, reflux, cramps or swelling at the next visit and ask which changes should prompt an earlier call.

Pause and ask

Do not massage a painful, hot or noticeably swollen calf while waiting to see if it passes.

Contact your care team

Contact your doctor or maternity team promptly

Some concerns need advice before the next routine appointment even when they do not feel like an emergency. If a symptom becomes severe, sudden or frightening, use urgent care instead.
