At 17 weeks pregnant, your baby is about the size of a mango and continuing steady growth. If you are searching for 17 weeks pregnant baby size or wondering about movement, this week often brings strengthening and greater awareness.
You are firmly in the second trimester. Energy may feel steadier. For many women, flutters become more recognizable.
Let’s look at what happens at 17 weeks pregnant.
At 17 weeks pregnant, your baby measures about 12 to 13 cm from crown to rump and weighs approximately 140 to 150 grams.
Here is what is happening:
