What to Expect at 9 Weeks Pregnant

Your Baby in Week 9

How Big is My Baby at 9 Weeks Pregnant?

When you’re 9 weeks pregnant, your baby is now just under an inch in length (2.3 cm) and weighs less than a tenth of an ounce (about 2 grams).

You can compare him or her to the size of a grape.

What Does My Baby Look Like at 9 Weeks Pregnant?

The fetal age of your baby is now 7 weeks.

This week, you are entering the third month of pregnancy, meaning that you are now 2 months pregnant.

Your child is starting to take on a more human-like appearance rather than a tadpole as previously.

A milestone this week is that the embryonic tail that your baby had up until this point has now disappeared.

The lips, nose, and eyelids continue to develop.

The eyelids are fused shut at this point and won’t open for quite some time until around week 26 (or sometimes a few weeks earlier, as seen in some ultrasound scans), even though the eyes are fully formed now.

Fetal Development When 9 Weeks Pregnant

Your baby’s development is intense right now. In addition to what actually been as described above, new little organs and features are being more and more developed hour by hour. It’s a fascinating journey!

Here are more of your baby’s milestones this week:

  • All of the essential body parts and organs are present and accounted for. The next weeks are for development and growth of everything that is already there. It goes so quickly, don’t you think?!
  • The four chambers of the heart have finished dividing and the valves are now forming, to prepare for the time to come.
  • Your baby’s heart is beating quickly at around 150 to 170 times per minute. This is about double the rate of yours. The heartbeat can usually be seen and heard in an ultrasound.
  • Even tiny teeth are formed under those gums, just waiting to come out later on.
  • Intestines begin to move out of the umbilical cord and into the abdomen as your baby grows and all of the “behind the scenes” action of ear development is finished.
  • Genitalia is also forming although you will not be able to tell for some time if it is a little boy or girl you will welcome into your home.

Mom’s Body

Your Belly in Week 9

You can probably feel that your belly has expanded a bit, and for some moms, it is soon time to shop for the first pair of maternity trousers. Or just use a bigger pair for a couple of weeks. Or – third and maybe the best choice, buy pant extenders. Such a smart invention!

You might have increased a bit in weight now, even though the baby, the placenta, the uterus, and so on, are not weighing very much yet. You can check what the pregnancy weight gain comprises of here.

Pregnancy Symptoms

Some women may now have known for weeks already and have gotten used to the idea of being pregnant, while others have been contemplating the many pregnancy symptoms with ifs and buts for the last few weeks.

Mood swings can be rampant at this point in your pregnancy, and you might feel happy one moment and emotionally exhausted the next.

All of the hormones can be hard on your system, especially if this is your first pregnancy. Each pregnancy is different and you may find that your moods are mostly triggered by your anxiety about a new addition to the family, especially if this is an unplanned pregnancy.

Other women may find that their moods ease up around 10 weeks and they feel a little more back to normal.

Textbook pregnancy symptoms can be more apparent now than ever before with tender, fuller breasts, nausea, and heartburn. If your morning sickness is really bad, “Beyond Morning Sickness” is a very helpful book.

You may also feel better by reading about the benefits of morning sickness here.

Even extreme fatigue can be a tip-off for those women who have yet to realize all that is going on within themselves. You can learn about more pregnancy signs here.

Pregnancy Announcement in Week 9?

Depending on how you feel and what your thoughts are, some women still choose to wait to announce their big news until after week 12, while other women want to announce it earlier, especially if you have now had an ultrasound scan that showed a live baby.

Taking your time to tell everyone is a personal decision and should not be rushed into if you are still unsure about telling your neighbor or even your parents.

Some women will let their best friends or sisters in on the secret while others have to wait. No matter what your preference is, it is just that; your own choice (OK, and that of your partner, of course. :-) )

If you are very worried about miscarriage, you can ask your midwife or OB/Gyn for an ultrasound. Studies have shown that if a beating heart is detected during the 8th or 9th week of pregnancy, the risk of miscarriage is low (below 2%), at least for pregnant women who are not bleeding and have not experienced repeated miscarriages before.

You can learn more about miscarriage statistics by week here.

What to Do this Week

Well, in addition to simply continue with self-care and prenatal vitamins, it is actually a good idea to start shopping around for maternity clothes. Especially trousers. As a start, you can browse maternity trousers at Amazon for inspiration.

If you are not ready for maternity trousers yet, but still have difficulties buttoning your jeans, get yourself some pant extenders asap. They are the smartest invention ever!

Pant extenders are great for the first trimester, and for the fourth trimester to – i.e. the first few months as a new mom, when you still kind of look pregnant.

If you are bothered by morning sickness, read up about efficient remedies, and make sure you eat frequently and drink enough water.

Diary of a Daughter

What’s it really like being 9 weeks pregnant…? Here’s a true diary from a 9 weeks pregnant mom (Me..!)

I was on my first visit to the midwife. She checked my iron levels, and they are low already. No wonder I’m tired!

The nausea is quite bad now, I’m practically nauseated all the time.
