Dizziness during pregnancy often kicks in at around week 17 in the second trimester. Blame hormones, your growing uterus and a rapidly expanding circulatory system.
Meanwhile, your little one is learning to suck and swallow, and is also starting to develop fingerprints.
Your Baby at Week 17
Hey Mom…It might be time for a high-five, because that’s how big your baby is this week — the size of your open palm. At a less-than-whopping three and a half ounces, your little one is starting to layer on some body fat, though she’s got a long way to go before she’s anywhere approaching plump.
From here on out your baby will accumulate fat until it makes up about one-third of her weight. That means by the time she makes her big debut, this skinny Minnie will be a relatively chubby cherub. But she’s not all lightweight. This week marks the first time your baby is bigger in size than the placenta that’s nourishing her. Now that’s something to brag about!
In other news, baby’s feisty little ticker is going full speed ahead thanks to another development this week. Until now, your wee one’s heartbeat was spontaneous and irregular. Now, her brain is in the driver’s seat, regulating her heart rate to 140 or 150 beats per minute. Take a listen — that steady sound will make your own heart sing.
Regularity is the name of the game these days as your precocious pupil is hard at work honing some key skills for her big debut. That includes making up and down movements of the chest wall in preparation for breathing actual air when the time comes. Sucking and swallowing sessions also make up a good part of her daily schedule now — and that’s a good thing. This way she won’t miss a beat when it’s time for that first delicious mom-made meal.
At a Glance
17 weeks pregnant is how many months?
If you're 17 weeks pregnant, you're in month 4 of your pregnancy. Only 5 months left to go! Still have questions? Here's some more information on how weeks, months and trimesters are broken down in pregnancy.
How big is my baby at 17 weeks?
My, how your baby has grown! Your little one weighs about 5 or more ounces and is the size of your palm, or around 5 inches long. Body fat (baby's, that is) is beginning to form and will continue to accumulate through the end of your pregnancy — join the club, baby!
Baby's practicing sucking and swallowing
Since practice makes perfect, your baby is sharpening his sucking and swallowing skills in preparation for that first and second…and third suckle at your breast or the bottle.
In fact, most of the survival reflexes your baby will have at birth are being perfected in utero right now.
Fingerprints are forming
Here's some proof that your baby is truly one of a kind — as if you needed any! Within the next week or so, the pads on your baby's fingertips and toes will become adorned with completely individual swirls and creases, aka fingerprints.
Baby's heartbeat is more regular
Baby's heart is now regulated by the brain, so no more random beats, and is churning out 140 to 150 beats per minute — about twice as fast as yours.
