Your short plan for this week

Do now

Make one list of prescriptions, painkillers, allergy remedies, vitamins, herbal products and recreational substances to review with a clinician or pharmacist.

Coming up

Tell the booking service about previous ectopic pregnancy, miscarriage, fertility treatment, long-term conditions or concerning symptoms because these may change early care.

Pause and ask

Do not stop a prescribed medicine suddenly because its leaflet mentions pregnancy; ask the prescriber how benefits and risks apply to you.

What you may notice

Your body and how you may feel

What is happening

For the support person

One useful thing a partner can do

  • Photograph or write down medicine labels and help make the first call if the pregnant person wants you involved.

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.
