When does the pregnancy monitoring process begin after a positive pregnancy test is achieved?

Once your clinic confirms your positive result, they will schedule your first beta hCG blood test 7 to 14 days after embryo transfer, and a second test 48 to 72 hours later to check for appropriate hCG doubling.

Specific monitoring Timeline

The happiest moment for patients who complete an IVF cycle in Thailand is getting a positive pregnancy test result. But the positive result is the starting point of a new chapter.

Once your clinic confirms your positive result, a structured monitoring process begins to ensure your pregnancy is progressing as it should. Your monitoring timeline typically includes:

1. Beta hCG Blood Tests (Weeks 4–5 of pregnancy)

Your first beta hCG test is scheduled 7 to 14 days after embryo transfer. A second test follows 48 to 72 hours later to check if your hCG levels are doubling appropriately.

For a day-5 blastocyst transfer, levels between 50-200 mIU/mL at 9-11 days post-transfer are considered reassuring.

Remember: The doubling trend matters more than any single number.

2. First Ultrasound (Weeks 6–7)

This scan confirms the pregnancy is inside the uterus (ruling out ectopic pregnancy). It checks for the fetal heartbeat, the key marker of a clinical pregnancy. It also confirms whether it is a singleton or multiple pregnancy.

3. Progesterone Support (Until Weeks 10–12)

Continue progesterone supplementation until your doctor advises stopping. Most clinics recommend continuing until approximately 10 to 12 weeks of pregnancy, when the placenta gradually takes over progesterone production.

Never stop progesterone on your own; always follow your doctor’s instructions.

4. Graduation to Regular Prenatal Care (Around Weeks 8–10)

Your fertility clinic will “graduate” you to a regular obstetrician (OB-GYN) or midwife. Before graduating, request a complete pregnancy record including hCG results, ultrasound reports, medication history, and your progesterone stop plan.

For Thailand IVF women returning home: Remember to request complete medical records in English from your Thai clinic before departure, and contact your home OB-GYN as early as possible to establish care.
