12 Weeks Pregnant: Your Checklist
- Maintain your healthy diet, especially as your appetite returns
- Keep brushing and flossing, even if you experience sensitive or bleeding gums
- Put together a budget for upcoming baby expenses
The truly critical period for your little one’s development is coming to a close, week 12 marks the end of your first trimester. By the end of this week, all of the body parts will be there; even the sex organs have developed (although it may be too soon from an ultrasound scan to determine whether you’re carrying a girl or a boy). Your baby has nearly doubled in size over the last three weeks, and his or her face has developed a human profile. Who will your baby look like? It’s still too early to tell!
A fetus at 12 weeks has fully formed eyelids. These aren’t just closed tightly; they’re actually fused together and will remain that way until late in your second trimester.
Baby is able to flex his or her tiny fingers now that your third month of pregnancy is coming to an end. Those little nail beds that recently developed are already starting to sprout fingernails and toenails, so stand by with a pair of baby nail clippers! Many infants are born with long fingernails that need to be trimmed soon after delivery.
Your fetus is reaching a new phase that will focus on maturation and growth. During the coming weeks, the tissues and organs will continue to develop while getting larger. Incredibly, baby’s tiny bones are already filled with marrow that is busy producing the white blood cells that will help fight off infections after birth! The heartbeat is usually audible with an external doppler at this stage, so you may get the opportunity to hear it at your checkup.
Your Baby’s Development
Your baby’s brain continues to develop, and tiny fingernails and toenails start to form. Vocal cords are formed this week, the last week of your first trimester.Watch Your Baby Grow
Your baby’s kidneys are functioning! After swallowing amniotic fluid, your baby will now be able to pass it out of the body as urine (pee). And the intestines will make their way into the abdomen because there is room for them now.
Has anyone told you that you have that “pregnancy glow”? It’s not just from the joy you may feel because you’re having a baby — there’s a physical reason for smoother, more radiant skin during pregnancy. Increased blood volume and pregnancy hormones work together to give you that glow. The greater blood volume brings more blood to the blood vessels and the hormones increase oil gland secretion, making skin look flushed, plumper, and smoother. Sometimes, though, the increased oil gland secretion can cause temporary acne.
Pregnancy symptoms at 12 weeks
It may seem strange, but your bleeding gums are actually a side effect of pregnancy. The hormones racing through your body can cause your gums to become easily inflamed, which is why they may bleed when you brush or floss.
However, bleeding gums can lead to more serious dental problems if you don’t treat them. Make you brush thoroughly twice a day, ideally using an electric toothbrush, and floss three times a week. You should also take advantage of your free NHS dental care during pregnancy and see your dentist for a check-up.
What you need to know at 12 weeks pregnant
- You’ll probably have your dating scan around now, if you haven’t already. And by the end of this week, your risk of miscarriage will be dramatically reduced. These milestones mean it’s time to think about telling the world that you’re pregnant.
- Letting your friends and family know that you’re expecting can be as low key or as high profile as you wish. You could plan a creative announcement to share on social media. Or you may prefer to tell your loved ones in person so you can see their reaction. Either way, enjoy your first chance to be openly excited about your pregnancy.
- You don’t need to tell your employer that you’re pregnant until 15 weeks before your due date. But letting people at work know your news does have its benefits. For example, your employer is required by law to make sure that you and your baby are safe at work. And you’ll find pregnancy symptoms much easier to cope with, when you don’t have to hide them.
