What Is a Transvaginal Scan (TVS) and When Is It Needed?

If you've been told you may need a transvaginal scan — or if it's been mentioned as part of your early pregnancy appointment — you might be wondering what it involves and whether it's something to worry about. The good news is that a transvaginal scan (TVS) is a routine, safe, and often more accurate way to see your baby in the very early stages of pregnancy. Here's everything you need to know.

What Is a Transvaginal Scan?

A transvaginal scan is an internal ultrasound scan carried out using a small, smooth probe that is gently inserted into the vagina. It sounds more daunting than it is. The probe is slender — roughly the size of a tampon — and is covered with a protective sleeve and ultrasound gel before use.

Because the probe is positioned much closer to the uterus and ovaries than a standard abdominal scan, it produces clearer, more detailed images — especially in early pregnancy when your baby is still very small. For this reason, it is often the preferred method in the first trimester.

When Is a Transvaginal Scan Recommended?

A TVS may be recommended in several situations:

• Early pregnancy (before 10–11 weeks) — when an abdominal scan may not yet give a clear enough view

• Suspected ectopic pregnancy — to check whether the pregnancy is in the right place

• Unexplained bleeding or pain in early pregnancy

• Suspected miscarriage or to confirm heartbeat after a previous loss

• Checking the cervix length during pregnancy

• Investigating pelvic pain or abnormalities

• When an abdominal scan gives an inconclusive result

At MyBaby Ultrasound, we discuss whether a TVS may be needed before your appointment so that you can make an informed, comfortable decision.

Does It Hurt?

Most women describe a transvaginal scan as uncomfortable rather than painful. The procedure is gentle and takes only a few minutes. You will be asked to empty your bladder beforehand — unlike abdominal scans, which often require a full bladder.

If at any point you feel discomfort, you can ask the sonographer to pause or stop. Your comfort and consent are always the priority. You are fully in control throughout.

Is It Safe?

Yes. Transvaginal ultrasound is widely used in obstetric and gynaecological care and has an excellent safety record. It does not use radiation and there is no evidence it causes any harm to you or your baby. The probe never goes near the pregnancy itself — it rests in the vagina, which is separated from the uterus by the cervix.

Transvaginal scans are routinely performed in NHS and private clinics across the UK, including during fertility treatment and early pregnancy care.

Do I Have to Have One?

No. A transvaginal scan is always offered on an informed consent basis. You will never be pressured into having one. If you decline, your sonographer will do their best to obtain a clear image abdominally. In some cases — particularly at very early gestations — a TVS may simply give a much clearer picture that allows us to confirm a heartbeat or check dates accurately, but the choice is always yours.

At MyBaby Ultrasound, we explain everything before we begin and always confirm your consent before proceeding with any internal examination.
