Week by Week Pregnancy 11 - 13 Weeks

These weeks mark the end of the first trimester and your baby is now the size of a plum. The facial features become clearer and the eyes, nose and ears move into their right places. Although the sex of the baby has been determined, the external genital organs may not yet be clearly visible on ultrasound. In addition, your baby's liver starts to produce blood and the kidneys produce urine.

For the expectant mother, these weeks are usually a time of reduced nausea and increased energy levels. However, some women may still feel tired. Sensitivity and bleeding of the gums may occur during these weeks due to pregnancy hormones, so it is important to take care of oral health.
