12 Weeks Pregnant | Pregnancy Week By Week


Here it is12 weeks pregnant! At the end of this week you will have survived the first trimester! Your hormones should start leveling off, making some of those early pregnancy symptoms much more bearable – especially the morning sickness! (Finally, right?) The 12th week of pregnancy is also the time when your risk of miscarriage drops significantly, so many people feel comfortable telling their friends and families about the pregnancy.

At 12 weeks, your baby is the size of a plum! He’s about 2.1 inches long and weighs around 0.49 ounces! The baby has grown at an amazingly fast pace so far. Over the last three weeks, your little one has nearly doubled in size, and all his major organs have developed. All that’s left to do now is to continue to grow!



You will be very excited to know that around week 12 is when most women’s morning sickness gets much better – it may even stop completely. You’re jumping for joy at hearing that, aren’t you? Just be careful! You don’t want to bounce that baby out just yet!

Although the morning sickness and some of the other symptoms you’ve been experiencing may calm down or go away, you’re not going to be completely symptom-free. Nope. Sorry to say, you’ll have symptoms of some sort all through your pregnancy. So, let’s talk about the pregnancy symptoms at 12 weeks.

  • Spotting. Spotting at various times throughout your pregnancy can be normal. It usually just means something irritated your cervix and made it mad. Having internal examinations at your OBs office and having sex are the two most common reasons why you may spot. If you’re worried, contact your OB, but generally, spotting is not concerning.
  • Increased discharge. Clear, odorless discharge is par for the course with pregnancy. Yuck, right? It’s okay, though. This discharge helps protect you from vaginal infections. If you notice the discharge has an odor or has changed color – specifically yellow, pink, brown, or greenish— you may have an infection or could be in preterm labor, so contact your OB right away.
  • Dizziness. Having dizzy spells? It’s okay. At 12 weeks pregnant, shifts in your hormones or changes in your blood pressure could leave you feeling dizzy. Sit or lie down until the dizziness passes. Drinking water and having a light snack can sometimes help combat the dizzy spells. As always, contact your OB if the dizziness concerns you.
  • Headaches. If it’s not one thing, it’s another when it comes to pregnancy. Starting at 12 weeks, you may experience more headaches than you have up till now. They’re caused by a few different things – low blood sugar, hormones, stress, dehydration, or lack of sleep. If you notice something that triggers the headaches, do your best to avoid that thing. If the headaches become severe (think migraines), contact your OB. Otherwise, you kind of have to suck it up and deal with it because it’s just another one of the joys of pregnancy!



At 12 weeks you more than likely have a noticeable baby bump. Aww! If you’ve been keeping your pregnancy a secret, that bump is going to make it a lot harder to keep that secret now!

Normal weight gain by 12 weeks pregnant is between 4 and 8 pounds. You may have gained a little more or little less than those amounts due to morning sickness, but you shouldn’t be worried about your weight unless your doctor finds it concerning. Just prepare yourself for the pounds you’ll put on as your pregnancy progresses!

As of right now, your daily caloric intake should not be much different from what it was before you got pregnant. You don’t want to overeat just because you’re pregnant (that old saying that you’re eating for two isn’t exactly accurate). As long as you’re eating foods that are good for you (you know, the kind that have vitamins and nutrients in them), and are limiting the junk food as much as possible, your weight gain should be right on track throughout your pregnancy, and the baby will get the nutrients he needs from you as well.



You may or may not have an ultrasound at 12 weeks pregnant, but if you were to have one, you’d see an image of your baby that really does look like a baby now. Your baby’s limbs and organs are developed by now and just need to continue to grow and mature over the next six months.

Right now, your baby can make a fist and wiggle those fingers and toes. He’s busy kicking and doing somersaults in your belly, though it’s still too early to feel those movements. Give it a few more weeks and you’ll start to feel everything!

His brain is developing very quickly, and all those little important organs are maturing by the day. If you have an OB appointment this week, you’ll probably get to hear his heart beating, too!

While it’s still too early to definitively make out whether your baby is a boy or a girl, the sex organs have developed already. When you go to have the anatomy scan done, usually around 20 weeks, you can find out if it’s a boy or a girl at that point. However, if you’ve had any chromosomal or genetic blood testing done, those results can tell you the sex of the baby if you’re dying to know already!



The main thing you should be doing at 12 weeks pregnant is resting! You’ll want to rest as much as you can throughout your pregnancy, because once the baby is born, rest isn’t something you’ll get very often.

Other things to do this week include:

  • Scheduling your next OB appointment, if you haven’t already.
  • Let your friends and family know about the impending arrival of your little bean.
  • Take baby bump progression pictures.
  • Start filling out your baby registry.
