Where is your uterus exactly?

Your uterus is in your pelvic cavity. To be precise, it is behind the bladder and for the rectum. She is held in place by means of ligaments. When you grow it a lot, it will be more dependent on these ties. This can cause that annoying tire pain.

It actually consists of two parts. One part is called the 'body'. The body is connected to your ovaries via the fallopian tubes. So you can go to the uterus after ovulation. The implantation of the egg takes place in the body of the uterus. The second part is called the cervix. The cervix is ​​the connection of the body to the cervix and then your vagina.

Normal size uterus

The size, if you are not pregnant, is similar to a pear. The shape also looks like a pear, but then vice versa. In centimeters, your uterus is 7.6 centimeters long, 4.5 centimeters wide (the body) and about 3 centimeters thick.

How do uterus feel pregnant?

The size of your uterus is a good indication for the growth of your child. And because of this the size can also indicate how many weeks you are pregnant. Your uterus is measured during your visits to the midwife. Here the position of the top edge is measured with respect to the pubic bone and the belly button. This is called the fund height.

In the first trimester the upper edge is close to the pubic bone. From the 12th week of your pregnancy, the upper edge comes from under the pubic bone and begins to grow more and more. From this week you can also feel the top edge yourself. Just lay flat on your back and then press your fingers over your pubic bone. You should feel a hard edge that feels like a ball. That's your womb!

From now on you will notice that your pants are getting tighter. The fund height is indicated in centimeters. This number of centimeters is equal to the number of weeks that you are pregnant with a margin of -4 to +4 centimeter. If you are 28 weeks pregnant, the fund height is between 24 and 32 centimeters.

Functions of the uterus

The uterus has 3 important functions in which implantation of the fertilized egg is actually the most important. Below the 3 functions.

  • Innestling

    Everything your uterus does has to do with the possible implantation. Ovulation takes place every month and the mature ovum enters the fallopian tube. Here the egg is fertilized or not. During this ovulation your uterus is preparing hard for a possible pregnancy by allowing the uterine lining to thicken. After ovulation and possible fertilization, the (fertilized) ovum goes to the uterus where it is implanted in the uterine lining. But if the egg cell is not fertilized, it is disposed of together with the uterine lining. You are therefore a period.

  • Protecting your child

    Your uterus protects your child against bumps and temperature changes by producing amniotic fluid. Your child can also move wonderfully in the amniotic fluid. The amniotic fluid also ensures that the waste materials of your child (at that moment embryo) is removed and infections can not reach your baby.

  • Childbirth

    You can not have a natural birth without your womb. The birth starts and is possible due to the contractions of the uterus. These are the contractions. The contractions ensure that the cervix becomes better and more accessible. These incipient contractions are called access problems. When you have 10 cm of access, the so-called extrusion phase begins. The uterus then contract more strongly. These contractions in combination with the pressing (of you) ensure that the baby is pushed through the birth canal.
