What’s Happening to Your Baby?
By week 12, your baby has graduated from an embryo to a fetus and is about the size of a plum!
✅ Organs Are Functioning: The kidneys, intestines, brain, and liver are working.
✅ Bones & Muscles Are Forming: Your baby’s arms and legs can now move!
✅ Facial Features Are Defined: Eyes have moved into place, and tiny ears are forming.
✅ Fingernails & Toenails Appear: Your little one is growing nails!
✅ Sex Organs Start Developing: Though it’s still too early for a gender reveal.

Your Changing Body – What to Expect in Month 3
Your body is working hard to support your growing baby. Here are common third-month pregnancy symptoms:
🔹 Decreasing Nausea: Morning sickness may ease up by the end of this month.
🔹 Increased Energy: Many moms-to-be feel less exhausted than in previous weeks.
🔹 Visible Baby Bump: You might notice a slight bump as your uterus expands.
🔹 Frequent Urination: The uterus is still pressing on your bladder.
🔹 Mood Swings & Emotional Changes: Hormones are still fluctuating, making you feel up and down.
Important To-Dos in the Third Month
✅ Start Sharing the News! Many parents wait until after the first trimester to announce their pregnancy.
✅ Book Your First Ultrasound. Around 12 weeks, many doctors perform a nuchal translucency (NT) scan to check for genetic abnormalities.
✅ Switch to Maternity Clothes. Your belly is growing, and comfortable clothing is a must!
✅ Keep Up With Your Prenatal Vitamins. Folic acid, iron, and DHA are essential.
✅ Plan for the Second Trimester. This is often called the “honeymoon phase” because energy levels improve!
