When is the gestation sac detectable via ultrasound?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

My wife has been experiencing slow-increasing beta hCG levels after attempting to conceive using Ovitrelle to trigger ovulation as recommended by our fertility specialist. She noticed sensitive breasts and took a pregnancy test, which showed the following beta hCG levels on different occasions: 29.9, 26.9, 49.1, 65, and 95 respectively. Despite having taken several transvaginal ultrasounds, nothing has been detected.

I am concerned about the potential causes, risks, and available treatments for this situation. Kindly help.

Thank you.

Hello,

Welcome to icliniq.com.

Thank you for your query.

I understand your concern. Yes, it is indeed too early to perform an ultrasound and detect the gestational sac at this stage of pregnancy. Waiting until around six to seven weeks for the scan is appropriate as the heartbeat can also be observed by then.

As for the beta hCG (beta-human chorionic gonadotropin) values, a gradual increase is normal at this early stage of pregnancy. It is essential for her to start taking folic acid tablets daily, as it is vital for the proper development of the fetus.

To provide further assistance, please provide additional information such as:

  1. Does she have any history of previous abortions?

  2. Is she currently on any medication?

  3. Does she have any pre-existing medical conditions?

With these details, I will be able to offer more accurate guidance and support. I hope I have addressed your concerns. Feel free to reach out if you have any further questions.

Thank you.

Patient's Query

Hello,

My wife has a medical history of an abortion, a previous miscarriage, and another recent miscarriage that stopped at eight weeks. There are currently concerns about a possible ectopic pregnancy. She also has a stable history of Basedow Graves disease without medication for the past 10 years. We attempted to conceive recently, but my wife had a normal period afterward. Since then, there has been a slow increase in beta hCG levels. Given the complexity of her medical history and the current concerns, we are seeking appropriate guidance and medical attention to address these issues effectively.

Hello,

welcome back to icliniq.com.

Yes, it is still early to see a significant increase in BhCG ( beta-human chorionic gonadotropin)levels, as the actual pregnancy may be around 1-2 weeks based on her dates. There is a possibility of ectopic pregnancy, but it's difficult to predict at this early stage.

Questions to consider:

  1. Did she have intercourse in the month of July?
  2. What is her average menstrual cycle length?
  3. Were the periods she got on the 29th with regular flow or just spotting?
  4. I recommend repeating the BhCG test on the 25th.

Considering her history of abortions, it would be better to start progesterone tablets as well.
