13 Weeks Pregnant | Pregnancy Week By Week

13 Weeks Pregnant | Pregnancy Week By Week


Yay! You’ve officially survived the first trimester of your pregnancy! Didn’t think you’d make it, did you? At 13 weeks pregnant, your hormones will start to settle down and become more balanced, so the morning sickness, fatigue, and mood swings you’ve been struggling with up to this point will get better. You may even begin to feel like your usual self again – except for your growing belly of course!

In the 13th week of pregnancy, your baby is the size of a lemon, coming in at about 2.9 inches in length and weighing around 0.81 ounces! Grow, baby, grow!



This is the week you’ve been waiting for since you started feeling sick and throwing up all the time – the week that should hopefully bring your morning sickness to an end! If you’re like most women, the pregnancy symptoms at week 13 will change. While the morning sickness and fatigue will get better – and possibly go away completely – you’ll still experience various symptoms that’ll make sure you don’t forget the fact that you’re pregnant. (You know, because it’d be so easy to forget that you’re pregnant with that ever-enlarging baby bump you’re sporting.)

Here are a few of the pregnancy symptoms you may experience in week 13:

  • Visible veins. Due to your increased blood supply, you may notice your veins can be seen more prominently. Don’t worry! The unsightly blue streaks all over your body will go away once the baby is born.
  • Constipation. Getting backed up is par for the course during pregnancy with all the changes your body is going through. If you’re struggling to have bowel movements, sneak some extra fiber into your diet to get things moving. If that doesn’t help, talk to your OB about other pregnancy-safe options.
  • Energy boost. Yep, that’s right. This is a good pregnancy symptom! After all these weeks of being too tired to breathe, much less get off the couch, you’ll finally gain that energy back and feel more like yourself again!
  • Increased sex drive. Yeah, baby! How you doin’? Finally, a pregnancy symptom you (and your significant other!) can be excited about! You may notice a little spotting after sex. This is generally nothing to worry about. It happens because your cervix is very sensitive right now. If you’re worried, though, give your OB a call to put your mind at ease.
  • Heartburn/Indigestion. Another uncomfortable symptom to deal with, but you can avoid the heartburn and indigestion as much as possible by eliminating the foods and/or drinks that trigger the burning sensation in your chest. It may also help to stay elevated a bit when lying down.



At 13 weeks, you’re probably beginning to look pregnant with that cute little baby bump popping out a little more each week. It may have seemed slow-going to get to the point where you could see the evidence of your pregnancy, but now things are going to pick up pace. Your uterus is going to continue to enlarge to make room for your growing baby, and if you haven’t gained much weight so far in your pregnancy, you’re going to catch up with that weight gain in the second trimester.

The ideal amount of weight to gain for a woman with an average BMI (body mass index) by the end of the pregnancy is 25 to 35 pounds. That comes out to about one-half to one pound a week that you need to gain. As usual, though, your doctor will let you know if there are issues with your weight gain. Just concentrate on eating well and staying as active as possible throughout your pregnancy.


You likely will not have an ultrasound at 13 weeks, unless you’re high risk and you receive routine ultrasounds to check on the baby’s development. If you were to have an ultrasound this week, you’d see your baby bouncing around, performing acrobatic maneuvers, and possibly even sucking his little thumb.

While there is a very small chance you’d be able to tell the gender of the baby at a 13-week ultrasound, those little parts can be hard to make out with 100% certainty. If your doctor gives you a guess as to the baby’s gender, take it with a grain of salt at this point. You’ll have an anatomy scan sometime between 18 and 20 weeks, during which you can find out more accurately if you’re having a boy or a girl.

If you’ve decided to go ahead with non-invasive prenatal testing, which is a type of DNA test that checks for chromosomal abnormalities, you’ll find out the gender of your baby at that time.



After surviving the past couple of months of morning sickness and fatigue, at 13 weeks you should have a little fun and relaxation. Get back to doing some of the things you may have put on hold because you just haven’t had the energy to do a whole lot. Here are some other things you should be doing at 13 weeks pregnant:

  • Continue taking your prenatal vitamins. Many women either forget to take their daily prenatal vitamin or slack off on taking it after the first trimester. Try and remember to take it every day because it provides your baby with important nutrients that will help him grow and develop so he’ll be ready to meet you when the time comes.
  • Wash your hands often. Pregnancy leaves you more susceptible to germs, meaning you could find yourself getting sick more often. To ward off as many of those germs as possible, be sure to wash your hands more often than you normally would. It’s no fun being sick, but it’s especially no fun being sick and pregnant!
  • Share your pregnancy news. If you haven’t already, you should start sharing the news that you’re pregnant with family and friends. You’re probably beginning to show, so it’s not as if you can keep it a secret much longer anyway! Let people celebrate with you!
