As you approach the end of your first trimester, you're probably eager to know what to expect at week 13 of pregnancy. This period is crucial for your baby's growth and development, and you're likely to notice significant changes in your body. At 13 weeks pregnant, you're almost at the end of your first trimester, and this phase is often referred to as the "golden period" due to the relief from morning sickness and the onset of a newfound energy.
During week 13, your baby is about the size of a peach, measuring approximately 2.9 inches (7.4 cm) in length and weighing around 0.81 ounces (23 grams). Their major organs and body systems continue to develop and mature, preparing them for life outside the womb.
