9 Weeks Pregnant: Your Baby’s Development

This week, your little one (now officially known as a fetus) is looking less and less like a little pink blob – especially since the tail has disappeared. With the trunk straightened and elongated, your little one is about an inch long this week.

This stage is a critical period for arm and leg development. The legs have lengthened and the buds that will eventually become the toes have started to sprout. Meanwhile, the arms have gotten longer and have begun to bend at the elbow. A basic hand structure is forming too with the fingers and thumb clearly differentiated. Your little one’s liver, gallbladder, spleen, and adrenal gland are starting to develop.

Now that you’re 9 weeks pregnant, your little one is suddenly on the go. It’s the beginning of the dance period, with vigorous movements occurring spontaneously and in response to stimuli from outside your body, such as light and noise. Try to be patient – you’ll have to wait until the second trimester to actually feel these movements when they happen.

How Big is Your Baby at Nine Weeks?

This week your baby is about the size of a cherry! The average 9-week fetus size is 0.75” – 1” long, with a weight of about 0.7 ounces.

Mom’s Body at 9 Weeks Pregnant

Symptoms include even more changes to your breasts as they make way for milk. Your breasts are probably fuller, heavier, and tender to the touch by now. Although they’ll continue to grow throughout your pregnancy, the sensitivity will usually subside by the end of your fourth month. You may start to see small white bumps on your areolas (the dark colored part of your nipple). These are glands called Montgomery’s tubercles, and they’ll produce oils to keep your nipples moist during breastfeeding.

If you weren’t active before you got pregnant, now is a great time to choose a safe activity you can stick with for the rest of your pregnancy. Swimming, walking, and yoga are all excellent choices.

Drop by the pool! Many experts consider swimming to be the best exercise for pregnant women, as it’s gentle on your joints. The hormone relaxin that’s now running through your body makes your joints loose so your pelvis can expand during birth. While this will help during your delivery, make sure to avoid exercises that could put too much strain on your joints in the meantime.

9 Weeks Pregnant: Your Symptoms

  • Growing Waistline – Your belly may not have a pronounced, rounded look – but your pre-pregnancy clothes are probably feeling pretty tight due to a combination of a thickening waistline and some bloating brought on by your old friends, hormones.

  • Visible Veins – Blood volume is increasing as your body nourishes your rapidly-growing baby, and this means that your veins may look more prominent.

  • Darkening Nipples – Your breasts may still be feeling uncomfortable and your nipples could look a little darker than usual.

  • Spotting – It’s still normal to see some spotting now, but at 9 weeks, bleeding can indicate that there’s a problem. Be sure to call your doctor right away if you see more than a few drops of blood.

  • Cramping – Nine weeks is a time of rapid change in your body, and your weight is shifting. If the cramping is severe or if you feel pain other than mild cramping and discomfort in your lower back, call your doctor to rule out problems.

  • Morning Sickness – If you haven’t experienced morning sickness by now, you’re probably one of the lucky few who will avoid this common symptom. Keep on eating little meals and remember to stay hydrated if this is among your symptoms.

  • Feeling Hungrier – You may start to feel a bit hungrier than usual at times. Keep extra snacks light; you should be adding about 300 calories to your daily intake.

  • Strange Food Cravings and Aversions – Your sense of smell is heightened now and things that you once enjoyed may seem unpleasant. Because your body needs great nutrition, you may be craving some interesting things. Give in to cravings if they seem healthy! Just watch your calories when you do.

  • Fatigue – Dizziness and fatigue are common issues at this stage. Rest as much as you can, particularly if you’re having some trouble sleeping at night.

  • Emotional Roller Coaster Ride – If you’re feeling on top of the world one minute and doomed the next, you can thank your hormones. They are still increasing and this leads to some feelings of instability.

  • Frequent Urination Continues – Yes, those extra trips to the bathroom are still part of your daily schedule. Avoiding caffeine can help a little bit, and so can leaning forward to ensure that your bladder empties completely. If you notice burning or pain with urination, call your doctor right away.

9 Weeks Pregnant: Things to Consider

  • Shop for maternity bras. They may not be the cutest items in the lingerie department, but they do offer extra support for sore breasts.

  • Work on your budget, and calculate the costs of continuing prenatal care and delivery, if applicable. Saving now means more for your family later on, so look for coupons, shop sales, and get your finances healthy while taking great care of yourself.

  • Be sure that you’re making wise choices about nutrition Good decisions now mean a healthier pregnancy for you and a healthier start for your little one.

9 Weeks Pregnant: Ask Your Doctor

  • Is it time for an ultrasound? Maybe so. If you already had one, you’re probably going to have to wait for a while. If not, this might be the week you see your baby for the very first time! Some doctors like to wait longer; it’s normal to get your first ultrasound between 8 and 12 weeks.

  • At 9 weeks, miscarriage risk can weigh heavily on your mind. Call your doctor right away for abnormal bleeding or any pain other than the mild cramping that should feel “normal” to you about now.

  • Call your doctor if you notice vaginal odor or increased vaginal discharge.

  • Gaining weight rapidly? It’s normal to begin gaining a little weight now, but it’s still not quite time to eat for two. Talk about ways to eat healthy without increasing your calorie intake too much.

  • Losing a little bit of weight? This might be a fact of life if you’re dealing with a terrible case of morning sickness. While it’s considered normal to lose a few pounds, now is not a good time to diet. Chat about ways to get your weight gain up to speed if this is a concern for you.
