You generally do not need to do anything extreme before a pregnancy ultrasound, but a few simple steps (like drinking water, wearing comfy clothes, and bringing your questions) can make the scan much smoother and clearer.

Quick Scoop: Key Things To Do

  • Drink water as instructed (often 2–4 glasses / about 16–32 oz) in the hour or two before many early transabdominal pregnancy scans so your bladder is comfortably full, which helps get clearer images of your uterus and baby.
  • For transvaginal scans, you’re usually asked to empty your bladder beforehand, because a full bladder can actually get in the way.
  • You can usually eat normally and take your usual medications, but follow any specific instructions your clinic gives you and ask if you’re unsure.
  • Wear loose, comfortable clothing (ideally a two‑piece outfit) so your belly is easy to uncover without fully undressing.
  • Arrive a bit early to handle paperwork and settle your nerves, especially if it’s your first ultrasound.
  • Bring a support person if your clinic allows it; many places encourage you to share the moment with a partner, friend, or family member.
  • Write down your questions in advance (about due date, what they can see at this stage, what’s “normal”), so you don’t forget them in the moment.

Before the Scan: Step‑by‑Step

  1. Check the type of ultrasound
    Your provider or booking message usually tells you if it’s transabdominal, transvaginal, or both, and whether you need a full or empty bladder.
  1. Follow bladder instructions
    • Early pregnancy transabdominal: drink the recommended amount of water (commonly 2–3 glasses or around 16–32 oz) 1–2 hours before, and try not to pee right before the exam.
 * Transvaginal: you’re usually told to empty your bladder just beforehand.
  1. Eat normally (unless told otherwise)
    Most pregnancy ultrasounds do not require fasting; you can typically eat as you normally would.
  1. Get your documents ready
    • Medical history, medications, allergies.
 * Insurance or ID, if needed.

 * Written list of questions or concerns.
  1. Dress for comfort and access
    Loose pants or leggings plus a top, or an easily lifted dress, make it simple to expose your abdomen.

You may be asked to remove jewelry or piercings from the area being scanned.

  1. Plan emotional support
    If allowed, bring someone you trust; many clinics also offer a chaperone if you prefer a staff member in the room.

What Not To Do Before a Pregnancy Ultrasound

  • Do not intentionally arrive with an empty bladder for early transabdominal scans unless you were clearly told to.
  • Do not skip fluids in the days before if your provider emphasised hydration, as good hydration can improve amniotic fluid clarity and image quality.
  • Avoid very tight one‑piece outfits that make accessing your belly difficult.
  • Do not be afraid to ask if you can take your regular meds; if any need to be stopped, that should come from your healthcare provider, not the internet.

Wear loose, two‑piece clothing Makes it easier to uncover your belly without fully undressing.
Bring questions and medical info Helps you get clear answers and avoid forgetting important details.
Arrive 10–15 minutes early Allows time for paperwork and to relax before the scan.

Tiny Story: First‑Scan Jitters

Many people describe shuffling into their first ultrasound “very hydrated,” feeling a bit awkward with a full bladder but relieved when they see how clearly the baby appears on the screen.

The mild discomfort of waiting to pee usually fades the moment the heartbeat or tiny movements show up and the room suddenly feels very quiet and very special.

Important: If you have pain, bleeding, feel dizzy, or are worried about something urgent, contact your healthcare provider or an emergency service right away instead of waiting for your scheduled ultrasound.
