At 14 weeks pregnant, your baby is about 3.5 inches long (measured from the top of the head to the bottom of the tailbone) and weighs roughly 1.5 ounces. That’s about the size of a lemon. You’re just entering the second trimester, and your baby is growing quickly from here.
Length, Weight, and How They’re Measured
The 3.5-inch measurement is what’s called “crown-rump length,” meaning it covers only from the top of the skull to the base of the spine, not the legs. Legs are still tucked and curled at this stage, so doctors don’t include them in the measurement until later in pregnancy. In weight, 1.5 ounces is roughly the heft of a small handful of grapes.
To put the growth rate in perspective, your baby was only about the size of a lime just one or two weeks ago. Over the next few weeks, length and weight will accelerate noticeably. By week 18 or so, your baby will have roughly doubled in length.
What Your Baby Is Doing at 14 Weeks
Your baby is actively moving at 14 weeks, stretching, turning, and flexing newly formed limbs. The catch is that you almost certainly can’t feel any of it yet. The fetus starts moving around 12 weeks, but those movements are too small and too cushioned by amniotic fluid to register. If this is your first pregnancy, you’ll likely feel the first flutters (called quickening) closer to 20 weeks. If you’ve been pregnant before, you might notice them around 16 weeks because you know what to look for.
Other developments happening right now include the early formation of fine, downy hair (called lanugo) across the skin, the beginning of facial expressions as tiny muscles develop, and kidneys that are starting to produce small amounts of urine. The roof of the mouth has formed, and the intestines are producing a waste substance that will become your baby’s first bowel movement after birth.
Can You Find Out the Sex at 14 Weeks?
If you have an ultrasound at 14 weeks, there’s a reasonable chance the technician can identify the baby’s sex, but it’s not guaranteed. Accuracy at 14 weeks by ultrasound reaches about 90%, and some research shows that scans performed after 14 weeks achieve nearly 100% accuracy. Earlier in the first trimester, the success rate drops to around 75% overall. If a clear view isn’t possible at your scan, your provider will likely suggest checking again at the anatomy scan, typically done around 18 to 20 weeks.
Blood-based screening tests (noninvasive prenatal testing) can reveal the sex even earlier with high accuracy, sometimes as early as 10 weeks. If you’ve already had one of these tests, you may already know.
Changes in Your Body
At 14 weeks, your uterus is transitioning out of your pelvis. Around 12 weeks it was about the size of a grapefruit and still tucked inside the pelvic bowl. Now it’s beginning to rise, and over the coming weeks it will settle midway between your navel and your breasts, roughly the size of a papaya. This shift is often when a pregnancy “bump” becomes visible, though the timing varies widely depending on your body type and whether you’ve been pregnant before.
You’re also entering the phase where steady weight gain becomes expected. For most people with a normal pre-pregnancy BMI, the recommended pace is about 1 pound per week through the second and third trimesters. If you started pregnancy overweight, the guideline is closer to 0.6 pounds per week; if you started in the obese range, about half a pound per week. Total first-trimester gain is typically modest, somewhere between 1 and 4.4 pounds, so the second trimester is when the scale starts moving more noticeably.
What 14 Weeks Feels Like for Many People
The transition into the second trimester often brings relief. Nausea and extreme fatigue from the first trimester tend to ease around this time, though not for everyone. You may notice increased appetite, more energy, and less breast tenderness. Some people experience a stuffy nose or occasional nosebleeds as blood volume increases. Round ligament pain, a sharp or pulling sensation on either side of your lower belly, can start appearing as your uterus grows and the supporting ligaments stretch.
Your next prenatal visit will likely involve routine blood work and possibly a discussion about upcoming screening tests. The detailed anatomy ultrasound, where your baby’s organs and growth are measured comprehensively, is usually scheduled for around 18 to 22 weeks. That scan provides a much fuller picture of how your baby is developing and a more reliable look at sex if you want to know.
