  • The bones, including the skeleton, skull, and long bones, are starting to harden and develop further.
  • Your baby’s fingernails are beginning to form, adding to their tiny developing hands.
  • Your baby’s vocal cords are in the process of forming, getting ready for the future ability to make sounds and communicate.
  • The liver plays an important role in producing red blood cells for your baby’s circulation.
  • The pituitary gland is starting to secrete hormones, contributing to developing and regulating various bodily functions.
  • Previously, the intestines extended into the umbilical cord, but now there is enough space in the baby’s abdomen for the intestines to move to their final position.
  • The placenta has become fully functional, taking over the production of hormones to sustain the pregnancy and support your baby’s growth.

12 Weeks Pregnant Symptoms

Here are the common symptoms you may experience at 12 weeks pregnant:

  • Expanding Uterus

Your uterus moves up and fills your lower abdomen, creating a slight protrusion called the fundus.

  • Skin Changes

About 75% of pregnant individuals notice skin pigmentation changes like melasma, which typically fades after pregnancy.

  • Reduced Nausea

Stabilizing hCG levels can relieve nausea, although some may continue to experience morning sickness.

  • Bladder Relief

As the uterus rises, it eases pressure on the bladder, reducing restroom visits.

  • Headaches

Hormonal changes, increased blood volume, and altered circulation can cause headaches.

  • Dizziness

Hormonal shifts, low blood sugar, or changes in blood pressure may result in dizziness.

  • Weight Gain

During the 12th week of pregnancy, you may start to notice some weight gain. 

  • Tender Or Sore Breasts

Your breasts may feel tender, sore, or even more sensitive during the 12th week of pregnancy. This is a result of hormonal changes.

  • Darker Areolas

Hormonal fluctuations darken the areolas, the area around the nipples.
