12 Weeks Pregnant

Your uterus is now appearing above the pubic bone, and through weeks 12 to 16 you will definitely start ’showing’. The good news is at about 12 weeks pregnant symptoms like morning sickness and fatigue may start to fade a bit soon, as your hormones start to calm down. But bad news is that headaches and dizziness may replace them 🙁 . Here’s more info about what’s happening to your body at 12 weeks pregnant:

  1. Increased discharge This clear discharge might seem weird, but it’s normal and has an important purpose: to protect your vagina from infection. But if you have yellow, greenish, pink, or brown discharge during pregnancy week 12, call your doctor right away. Those colors could be a sign of infection or preterm labor.
  2. Spotting Spotting or bleeding during pregnancy at 12 weeks could be worrisome—or it could be nothing at all. For example, your cervix is more sensitive during pregnancy, so simply having sex could cause light bleeding that’s harmless. If you’re spotting or bleeding, definitely tell your doctor. If the bleeding is accompanied by cramping or the flow is heavy, it’s an urgent call.
  3. Headaches These may start to intensify around week 12 of pregnancy. Headaches may be caused by hormonal shifts, drops in blood sugar, dehydration, lack of sleep, or stress. To deal, pay attention to what might be triggering your headaches and try to avoid those culprits. If you notice a drastic increase in headaches or a type of headache you’ve never experienced before (such as a migraine), or if your headaches are accompanied by other weird symptoms, let your OB know.
  4. Dizziness Hormone shifts and blood pressure changes could cause dizzy spells around pregnancy week 12. You can help prevent dizziness by snacking regularly and drinking plenty of water. Sit or lie down if you’re feeling dizzy or lightheaded and let your doc know about any severe bouts.

If you’re 12 weeks pregnant with twins, you may still be experiencing morning sickness, while your singleton mom-to-be counterparts are likely starting to see the light at the end of the nausea tunnel. But know that things will likely to improve soon.

Development of Baby

At week 12, from head to toe, your baby is just over 2 inches (5cm) long and weighs .5 ounces (14 grams). The baby is as big as a plum. Now that baby’s got pretty much all his or her important organs, his or her main job is to keep on growing.

By now, your fetus  is almost done developing his or her body’s important systems and parts, which means it’s all about getting bigger and more mature from here on out. Yep, baby’s about to enter the growth and maturation stage, in which organs and tissues will grow and develop rapidly.

Vocal cords form during this week. The nails on all 20 fingers and toes form and become visible. The intestines are still growing and are moving into the abdominal area. opening and closing his or her fingers and curling toes.

More features on the face are starting to appear, such as the eyebrows and lips.

The umbilical cord helps to circulate blood. The brain continues to develop as it makes hormones of its own and the nerve cells multiply rapidly. Muscles start responding to impulses from the brain. As the brain and muscles develop together, natural movements such as bending of the arms, clenching and opening of the fists, and twisting of the wrists and elbows become easier and more frequent.


Around week 12, you might want to know more about baby’s health, so you may have genetic testing done to determine the risk of birth defects or other problems. This can be a little scary—and confusing—so be sure to ask your OB plenty of questions, and know that it’s much more likely baby’s A-OK than anything else.

It’s important that you continue to take care of yourself and your baby.

If pregnancy related symptoms such as fatigue, morning sickness and general nausea have not disappeared or at least reduced, you should let your healthcare practitioner know, as this could be a sign of a thyroid condition, multiple pregnancy, or a molar pregnancy, especially if bleeding or spotting is detected.

A molar pregnancy, also referred to as water filled cysts, occurs due to abnormal development of the placenta. It could cause a miscarriage at this stage of the pregnancy.
