Your baby this week
Your baby can sense light now! Even though the eyelids are still sealed shut, your baby will turn away if you shine a bright light on your belly. The tiny bones in the ears are forming, and your baby is starting to hear muffled sounds from the outside world. The legs are longer than the arms now, and your baby is doing somersaults, flips, and twists — building muscles for the big day.
Your body this week
Your heart is pumping about 20% more blood than before pregnancy. You may feel it racing occasionally — this is normal. Increased blood flow to mucous membranes may cause nosebleeds and gum bleeding when brushing. Your bump is more noticeable now. If this isn't your first pregnancy, you may start feeling fluttery movements called 'quickening' — like little butterflies inside.
Common symptoms this week
Every pregnancy is different — you may notice some of these, all of them, or none at all. None of this is a checklist to worry over.
