How Big is Your Baby at 9 Weeks?

Your baby is around .91 inches long and weighing in at .07 ounces. That’s about the size a Hershey’s Kiss.

Here’s what else to know when you’re 9 weeks pregnant:

Your Baby’s Development at 9 Weeks

Though it might sound like a message from outer space, that sound is actually your baby’s fetal heartbeat. And if you haven’t heard it yet, you soon will: most fetal heartbeats can be heard between 8 and 12 weeks. For some, hearing the heartbeat for the first time is thrilling. But there’s no right way to feel…

  • Heart development: Your baby’s heart now has four distinct chambers, and its valves are forming. That heartbeat may now be strong enough to be heard with a fetal doppler.
  • Eyes: Your baby has eyes that are fully formed now, too, but they won’t open for a while. In fact, the lids will be fused shut until about 27 weeks.
  • Arms and legs: Bones and muscles are starting to develop. Help those bones develop by getting enough calcium and vitamin D. Soon, your body will be supplying baby the calcium they need through the placenta. Aim for about 1,000 milligrams (1 gram) of calcium per day to make sure you have enough for your baby without depleting your own supply (which can lead to bone loss). Vitamin D helps your body absorb all that calcium; take about 200 to 400 IUs of it daily.
  • Fingers and toes: Those webbed buds on your baby’s hands and feet are starting to turn into actual fingers and toes.
  • Weight gain: Baby’s about to undergo major growth. Over the next three weeks, they’ll double in length, and will go from about .07 ounces to .49 ounces. That’s seven times their weight!

Top Tip for 9 Weeks Pregnant

There are lots of baby essentials, and a viral pregnancy announcement isn’t one of them. Do it your way!

Your Body: 9 Weeks Pregnant Symptoms

If you’re 9 weeks pregnant with no symptoms, cross your fingers—you may breeze through without morning sickness. If not, know that the tough times hopefully will pass soon. In the meantime, here are some of the symptoms you may experience during week 9.

  • Morning sickness: Nausea and vomiting can peak around 9 weeks pregnant. For many, it’s rough right now. But the symptoms should lessen soon, and you hopefully you’ll be totally done with it early in the second trimester. Keep doing whatever helps, whether that means constant snacking, sucking on lollipops or mints, or sipping lemon sparkling water.
  • Fatigue: Nodding off in important meetings and while binge-watching Stranger Things? Fatigue is one of the most common symptoms during the first trimester. As your body surges with progesterone, you get sleepy. Take naps, go to bed early and sleep in on the weekends. Just like with morning sickness, do what you need to do to get through.
  • Cramping: This usually is not sign of a problem. Cramping at 9 weeks pregnant could be due to dehydration, digestion issues or your growing uterus moving things around in there. If the cramps are severe or get worse, though, be sure to call your doctor.
  • Headaches: Pregnancy headaches are common for a variety of reasons, like hormone fluctuations, stress, vision changes, lack of sleep, dehydration and hunger. You can try to prevent them by getting rest, drinking plenty of water, snacking frequently and trying relaxation techniques, like meditation or prenatal yoga. Check with your doc to see what headache medications they approve for you; many give the OK to taking Tylenol for a particularly nagging headache.
  • Mood swings: Morning sickness can make you moody. So can those pregnancy hormones—some of them are messing with the parts of your brain that normally help you stay calm and collected. If you can, make things easier on yourself—at least for the next couple weeks, when moodiness is hitting hard. Reschedule social engagements for the second trimester, ask for help around your home and get extra sleep. (Do you detect a theme here?)
  • Frequent urination: Running to the bathroom to pee every 20 minutes? Frequent urination is really common during the first trimester because the hormone hcG (same one that causes the nausea) is causing extra blood flow and making your kidneys produce up to 25% more urine than usual. This symptom usually goes away in the second trimester, but it will probably come back when your baby gets big enough to dance on your bladder.
  • Weight gain at 9 weeks pregnant: Doctors usually recommend gaining about 1.1 to 4.4 pounds in the first trimester. If you’re pregnant with twins, you may gain 4 to 6 pounds. But if you’re under or over this, don’t freak out. Just talk with your doctor to make sure you’re getting the nutrition you need, especially if you’re having trouble keeping food down.

Fun Fact

Placenta comes from the word cake in Latin. Tasty?

Your Life at 9 Weeks Pregnant

At the start of month three, your pregnancy is getting real and so are your symptoms. There’s no magic cure (sigh), but these tips should help make life a little easier.

  • Top tip: Keep snacks at the ready—we’re talking in your nightstand, your desk drawer, your purse, your car. Some people swear that avoiding an empty stomach means avoiding feeling sick. Try eating something before you even get out of bed in the a.m. Who cares about the crumbs?
  • Gear to consider: Pants feeling snug? At 9 weeks pregnant, you may not be ready for maternity pants yet, but if that button on your jeans keeps popping open, pants extenders might just be your new BFF. Super handy, they’ll keep in your regular clothes a few weeks longer.
  • Recipes to try: If you want to up your calicium intake to help support baby’s growing bones, check out these tasty recipes. Three words: mac and cheese (assuming you can stomach it!).
  • Books we love: Looking for a good distraction from the quesies? Sally Rooney’s Conversations with Friends and Normal People might just fit the bill. They’re beautifully written page turners.

  • Make a plan to announce to friends/work/Facebook/Instagram/your second grade teacher that you’re expecting.
