Tu Bebé a las 15 Semanas

A Closer Look at Week 15

At 15 weeks, your baby is about the size of an apple and is developing an early sense of sight — even though the eyelids are still fused shut. The retinas have become sensitive enough to detect changes in brightness, and if you shone a torch directly at your belly, your baby might actually turn away from the light. This light sensitivity is one of the first signs of the sensory system coming online.

Body proportions are shifting noticeably this week. The legs have surpassed the arms in length, bringing the body closer to its birth-day proportions. All of the major joints — hips, knees, elbows, wrists, shoulders, and ankles — are fully functional and moving freely. Your baby is now capable of quite complex movements, including somersaults and stretches, though most mothers won't feel them for another few weeks.

You may notice some unexpected symptoms around this time, particularly bleeding gums when brushing your teeth or spontaneous nosebleeds. These are caused by the dramatic increase in blood volume that occurs during pregnancy — your body is now circulating approximately 20% more blood than usual. The extra blood flow makes the delicate blood vessels in your gums and nasal passages more prone to bleeding. Using a soft-bristled toothbrush and being gentle when flossing can help minimise gum bleeding.

Dental health during pregnancy is more important than many people realise. The hormonal changes that cause gum sensitivity can, if left unchecked, develop into pregnancy gingivitis — a mild form of gum disease. Research has linked untreated gum disease during pregnancy to preterm birth and low birth weight, so booking a dental check-up is genuinely important and not just a routine suggestion.
