Month 3 (weeks 9 through 12) Your baby's arms, hands, fingers, feet and toes are fully formed.

The beginnings of teeth are forming under the gums.

You'll probably start feeling your baby move between 16 and 22 weeks, most likely when you're sitting or lying quietly. Experts say none.

The top of your uterus is about halfway between your pubic bone and your navel, and the round ligaments that support it are thickening and stretching as it grows.

Baby development at 16 weeks

Pregnancy symptoms during week Fatigue. By this week, fatigue has probably set in again, though maybe not with the same coma-like intensity of your first trimester. Your tiredness is perfectly understandable, given the physical strain you're under and the restless nights of frequent pee breaks and tossing and turning while trying to get comfortable. While some women notice "quickening" this early, most don't feel their baby move until 18 weeks or more. (If this is your first baby, you may not feel movements until 20 weeks or so.) The first movements may feel like little flutters, gas bubbles, or even like popcorn . Though the external genitals in both male and female fetuses still have a way to grow, you'll be able to find out your baby's sex via the second trimester ultrasound, also known as the anatomy scan, usually scheduled for anytime between 18 and 22 weeks. You'll also get a detailed sneak peek at baby's other major organs and measurements and make.

List of Partners vendors. While it may sometimes seem like not much is going on and quite the contrary at other times , each week brings changes big and small that help your baby develop and your body prepare for labor, delivery, and beyond.

Pregnancy is marked by three trimesters. The week by week articles that follow in this guide provide a glimpse into all you can anticipate in these distinct and important phases of your pregnancy, including:. Whether you're a first-timer or an experienced mom, you may find pregnancy to be incredible, confusing, overwhelming, and everything in between sometimes at the same time.

Partners can find a special section dedicated to them each week, too. Start by reading on to get a sense of what each trimester entails, then dig into the individual week by week articles for a closer look at what a difference seven days can make. May your nine months of pregnancy be the healthiest and happiest they can be.

The reason? Home pregnancy tests generally will not register a positive result until about week 4. The first trimester is considered the shortest since it takes about 4 weeks for many women to realize they're pregnant.

Moreover, week 1 and week 2 are actually the weeks you ovulate and have your menstrual period. So, while the duration of pregnancy consists of 40 weeks, the countdown starts roughly two weeks before you officially become pregnant. Confusing, we know. While you may experience some belly changes, this is usually due to pregnancy-related bloating and gas, not baby growth.

Day one of your pregnancy, the sperm and egg have yet to meet. By the close of the first trimester, your baby is more than 3 inches long and sports arms, legs, eyes, a beating heart, and more.

For most moms-to-be, the middle trimester is considered the easiest. The reason: Your newly-formed placenta is generating more progesterone, a hormone needed to keep your uterine lining baby-friendly. This progesterone-boost coincides with a decrease in the production of symptom-causing hCG.

As such, you may feel like your pre-pregnancy self again, enjoying an uptick of energy and appetite. Regardless of your appetite, most women can expect to gain about one pound a week during the second trimester, putting total weight gain at about 12 to 14 pounds by the end of week The second trimester is considered the easiest due to a progesterone boost that creates an increase in energy and appetite.

For instance, as your trimester nears its end, you may start to feel practice uterine contractions, called Braxton Hicks. Hormones continue to flow, and your baby steadily grows, taking up more and more room and forcing your body to accommodate.

While every woman is different, here are some not-so-welcome pregnancy side effects you may be faced with during your second trimester:. Though not painful, you may also notice varicose veins and skin changes , such as mole growth and stretch marks. Their soft and flexible skeleton begins to ossify, or harden. By roughly week 22 , a tiny heartbeat can actually be heard if your partner puts their ear to your abdomen—perhaps some hiccups, too—since your baby is busily swallowing amniotic fluid now.

Many exciting milestones take place during the second trimester, including a visible baby bump, your baby's first movements, and learning your baby's sex if you choose. Maternity clothes are now in full rotation. You may show—and feel movement—a couple of weeks earlier if this is not your first child.

By the end of your second trimester, your baby looks a lot like the person you will meet at week 40 , albeit much smaller and more wrinkly. While you may be pregnant for the entirety of the third trimester, the majority of women go into labor between week 37 and week 39 , with the rest going earlier or as late as 42 weeks.

About half of twin pregnancies deliver before 37 weeks. The third trimester may be your hardest as you adjust to the emotional changes of birth and motherhood. No matter which category you will fall into, the literal heft of your baby and the emotional load of your impending birth and changing role make this final leg of pregnancy the most physically and emotionally challenging. This steady uptick of the scale continues for about two more months.

Then, around week 37, your total weight gain will likely hold steady between 25 and 35 pounds. The increase of total weight, plus the fact that your belly is pulling your spine forward, can amplify back pain.

Meanwhile, your crowded and ballooning uterus is putting pressure inside your abdomen, possibly spurring hemorrhoids. Your uterus is also likely pressing on your diaphragm, hindering breathing and increasing heartburn.

At the same time, your lungs and intestines have also shifted positions in order to accommodate your growing baby. Enjoy the fun! This trimester may be the most challenging, but it's also filled with exciting milestones.

When your partner places his or her hand on your belly, they can now feel your baby move from the outside. For many moms-to-be, this is also when the shower is thrown, the nursery is put in order, and nesting kicks in.

This is a time of accelerated growth and finishing-touches development. Your baby will have gained roughly 5 pounds in the 12 weeks that make up this final trimester, starting at just over 2 pounds and being born at roughly 7 pounds.

And it continues maturing throughout this trimester, growing by a third between week 35 and week By week 39, your baby will not become any more physically ready for birth. Instead, they use this time to properly position themselves for labor. If everything goes according to plan, you will deliver at around 40 weeks, though many women do so before or after. Your delivery may follow your birth plan to the letter or look entirely different than you have imagined it, perhaps, ending in a C-section when you intended to have a vaginal birth.

Regardless, your body if not your mind has been preparing for this moment throughout the course of your pregnancy.

Take comfort that you have selected a healthcare practitioner that you can count on, lean on your support team, and communicate your wishes for pain management and more. Reading more about the final weeks of pregnancy in this guide can help you better understand different labor and delivery scenarios and what you can expect, both during and after.
