A beta HCG test is conducted approximately 2 weeks after embryo implantation. If the test is positive, a follow-up test is conducted 48-72 hours later to monitor hormone levels. Around week 7 of gestation, a confirmatory ultrasound is performed. At week 10, the latest non-invasive prenatal testing (NIPT) is conducted to screen for chromosomal issues of your baby early in the pregnancy. Monthly ultrasounds will then be performed throughout the pregnancy.
