    At 15 weeks pregnant:

    • Your baby is the size of an orange
    • You’re in month four, five more.
    • The countdown continues: you’ve got 25 weeks to go!

    What happens during the 15th week of pregnancy?

    • You’ve got a little fuzzball growing — hair is beginning to appear with the growth of you baby’s eyelashes, eyebrows and a tiny amount on their head.
    • I see you baby the skin is developing, but it's so translucent that you can see the blood vessels just below the surface.
    • Bust a move — your baby is getting active in there, being able to move their arms, wrists, head, hands, feet, and wiggle their fingers and toes.
    • Take a deep breath — your baby can now make breathing movements, suckle, and swallow.

    What should I be feeling at 15 weeks pregnant?

    • By this week, you may be susceptible to what is known as pregnancy or baby brain, a vagueness or forgetfulness that happens to mothers it won’t last forever, but it’s a good excuse for little things you may forget right now.
    • This is the best time in your pregnancy so far you’re likely not feeling sick or so large that it’s uncomfortable, so sit back and enjoy the ride.
