So I believe you have heard a lot about the pregnancy trimesters, but what exactly happens during these stages of pregnancy development? Read on to find out!

Pregnancy Stages

A normal pregnancy lasts about 280 days (approximately 40 weeks), counting from the first day of last menstrual period. However, the normal limit varies from 259 to 294 days (37 to 42 weeks). The 40 weeks of pregnancy are divided into three quarters of 12 to 13 weeks (or three months) each:

First quarter: months 1 to 3
Second quarter: 4 to 6 months
Third quarter: months 7 to 9

Changes in your body will happen during your pregnancy. So, let me tell you what would be those changes you would be experiencing during the 9 months of your pregnancy.

If this is your first pregnancy, the pregnancy stages will surprise you.


  • After missing your period and ensuring that you are pregnant, your menstruation will stop.
  • Your breasts will begin to grow and be more sensitive because they will be preparing for breast feeding your baby, Look at some breastfeeding tips. Perhaps you will have some discomfort because you are not used to have your breasts bigger than usual, but do not worry. Breasts can increase to a size more in the first two months.

  • You will have the need of going to urinate more often. Will this be a problem? Of course not, do not worry. This sensation to urinate is normal to start from the sixth week of pregnancy. This is because the increased blood flow causes your kidneys have to process more fluid which goes into the bladder. However, if you feel urgently going to urinate, feel some burning, and only a few drops go out, you should consult your doctor because you might have a urinary infection. Minor infections are also common during pregnancy stages, but it is better the doctor evaluates this particular situation.
  • You will feel more tired. Is it normal to feel tired? You have started a divine process of nature and the formation of a new baby. There is in your stomach a lot of work, an amazing process to build that beautiful baby. The weight gain due to all new components of your body, like the placenta, amniotic fluid, tissue uterine, and bigger breasts are definitely a reason to feel tired, and you will get used during your pregnancy.
  • The terrible nausea and vomiting. There are some women who don’t even feel this discomfort, or it is very rare. I can tell you that I was one of those privileged women. However, most women believe it’s the most disgusting of pregnancy. That’s true, it is quite annoying. These changes are the result of the hormones in the placenta, especially progesterone and chorionic gonadotrophin. These hormones cause the digestive process to be much slower and therefore more time food remains in the stomach. Read more about: vomiting and nausea during pregnancy stages.
  • You will feel anxiety and sometimes the desire to eat an appetizer, some strawberries, peaches, nuts, even a snack. With all due permission, you can eat it without feeling guilty. During pregnancy is very important give yourself the pleasure to eat some snacks, in moderation of course, otherwise you can sometimes feel more nausea and even some terrible pains in your stomach. As long as you eat in moderation, and following a healthy diet, you can have the pleasure to eat anything you want.
  • If you have not feeling before symptoms of heartburn and indigestion, you may be suffering of this discomfort during pregnancy. Why this happens? Heartburn occurs because the gastric acid from the stomach back up into the esophagus (tube between the mouth and stomach), and this produces the sensation of heartburn or burning that begins in the stomach and seems to go up. Read more about: Heartburn During Pregnancy.
  • Another change that you may feel during pregnancy stages is constipation. This is the result of pregnancy hormones that cause the intestines to slow down their work and throwing debris becomes slower. My doctor recommended walking, drinking lots of water and eat food high in fiber. She also gave me medicine. I suggest consulting your gynecologist for a prescription.
