37 Weeks Pregnant

In the 37th week of pregnancy, the baby is already stuck into the pelvis, so it is likely that you feel fetal movement and activity has diminished significantly. However, you may feel considerably uncomfortable, experiencing even sleep issues and difficulty walking.

Provided below is an index with the 3 points we are going to expand on in this article.

Symptoms to expect

Your uterus (womb) is starting to mature, which causes greater amounts of vaginal discharge. If you feel that your vaginal discharge has become more viscous and stickier lately, or if you've experienced a mild spotting, it is likely that the mucus plug that lodges in the cervix to block the cervical canal is coming out.

Nonetheless, it can take several hours or even weeks from this moment until labor, so do not worry at all. If bleeding is heavier than your normal periods, your should visit your doctor as soon as possible.

You may notice that Braxton-Hicks contractions occur more frequently, or last longer. On the contrary, fetal movement is considerably reduced, since the baby-to-be has little room for moving freely. In spite of that, you should feel little movement. In case fetal movement vanishes completely, ask your doctor to dismiss the possibility of placental insufficiency.

How is the baby?

Throughout this week, your baby may "rehearse" breathing movements, even though there is no air in his lungs yet. This causes the amniotic fluid to enter into his windpipe, causing hiccup.

Also, the lanugo that covered his body completely has disappeared at this stage, except for the shoulders and the upper part of the arms.

At this point, your baby measures 48 cm long and weights about 3.100 g on average. A weight that ranges between 2.520 and 3.670 g is considered a normal range.

We make a great effort to provide you with the highest quality information.
