How many months is 9 weeks pregnant?

9 weeks pregnant puts you in month 3 of pregnancy. Week 9 is the first week of that month, which runs to week 13. Providers count in weeks; months are approximate.

How big is the baby at 9 weeks?

At 9 weeks, the baby is about the size of a grape, roughly 2.3 cm long and around 2 g. That is an average; healthy babies vary.

Why is week 9 of pregnancy often the hardest?

For many people, nausea is at its worst around now. In a study of 363 women who kept daily symptom diaries, 8 in 10 had nausea or vomiting, and symptoms peaked in the ninth week. The pregnancy hormone hCG is also at or near its highest level, and tiredness and sore breasts add to it. For most people, sickness clears up by 16 to 20 weeks. Get help if you can't keep fluids down for 24 hours, haven't peed for 8 hours, feel dizzy or faint, or vomit blood.

Where is the baby located at 9 weeks pregnant?

Very low down. At 9 weeks, your womb is still inside your pelvis, below the level of your pubic bone, so you can't feel it from the outside. The baby floats in a fluid-filled sac inside the womb, linked by the umbilical cord to the growing placenta. As the womb grows, it rises: the top reaches your pubic bone at about 12 weeks, sits about halfway to your belly button at 16 weeks, and reaches your belly button at around 20 weeks.

Is cramping normal at 9 weeks pregnant?

Yes, mild cramping a bit like period pain is common at 9 weeks as your womb grows. Constipation and trapped wind are common in pregnancy and can cause belly pain too. Pain is probably nothing to worry about if it is mild and goes away when you rest, change position, have a poo or pass wind. Contact your provider or maternity unit straight away if cramps come with bleeding, lower back pain, pain when you pee, or unusual discharge. Do the same if severe pain doesn't ease after 30 to 60 minutes of rest.

Is it normal to bleed when I wipe at 9 weeks pregnant?

It can be. Light spotting is fairly common in the first trimester. In a US study that tracked over 4,500 pregnancies, most bleeding episodes lasted less than 3 days, and only 8% of women who bled had heavy bleeding. Still, tell your provider or maternity unit about any bleeding at 9 weeks, so they can decide if you need a check. Call emergency services if you are soaking a pad quickly, or if bleeding comes with severe tummy pain, shoulder pain, or feeling faint or dizzy.

If I'm 9 weeks pregnant, when is my due date?

Your due date is 40 weeks after the first day of your last period, so at 9 weeks you have about 31 weeks to go. To find the exact date, add 280 days to the first day of your last period, or use our due date calculator. Your first scan may adjust it: from 9 weeks on, the date is usually changed if the baby's measured size and your period dates are more than 7 days apart. A due date is an estimate, so your baby may arrive before or after it.

9 Weeks Pregnant

At 9 weeks pregnant, your baby is about 2.3 cm long from head to bottom, around the size of a grape. The face is becoming recognisable, with eyelids, a mouth and a tongue with taste buds. The genitals are starting to form, but the sex can't be seen yet. The pregnancy hormone hCG is at or near its peak, and many people find their nausea at its worst now. This page covers what a 9-week ultrasound shows, where the baby sits in your body, why week 9 can feel so hard, what cramping and spotting usually mean now, and how to work out your due date.

What trimester is 9 weeks?

Week 9 is in the first trimester, which runs from week 1 to week 12. The second trimester starts at week 13, 4 weeks from now.

Baby development at week 9

This is the last stretch of the embryo stage: at the end of next week (week 10) it will officially be called a fetus. The essential organs are in place and now begin maturing. Tiny muscles are forming, allowing the first small movements. The face continues to refine, with eyelids, a mouth and a tongue with taste buds. About the size of a grape.

What an ultrasound shows at 9 weeks

By 9 weeks, a scan shows a clear head and body, with arms and legs now long enough to see. Small body movements can often be seen too. In one scan study, movements were seen in every normal pregnancy after 8 weeks. The heart is beating close to its fastest: about 170 to 175 beats per minute at the start of week 9, easing slowly to about 166 by week 12.

The sonographer may also see a small bulge where the umbilical cord joins the baby's belly. This is normal at this age. For a few weeks, part of the gut grows out into the base of the cord. In one study it was seen in every baby scanned at 9 and 10 weeks, and in none by 12 weeks, once the gut had moved back inside.

The crown-rump length measured now dates your pregnancy well. From 9 weeks, your due date is usually changed only if the scan and your period dates are more than 7 days apart. A normal 9-week scan is also very reassuring: in one study of women without symptoms, only 0.5% of those with a heartbeat at 9 weeks later miscarried. It won't show whether you're having a boy or a girl. That usually has to wait for the mid-pregnancy anatomy scan, between 18 and 22 weeks.

Your belly at 9 weeks

Most people don't show at 9 weeks. Your womb grows from about the size of a lemon at 7 weeks to about the size of a large orange by 10 weeks, but it still sits deep in your pelvis. Its top only reaches the level of your pubic bone at around 12 weeks. So if your belly looks bigger, bloating and a thickening waist are the likely reasons.

In a first pregnancy, a clear bump often doesn't appear until well into the second trimester, and for some people not until after 20 weeks. People who have been pregnant before may start to show sooner, from about 12 to 14 weeks. A 9-week belly can look very different from one person to the next.
