What are the symptoms of pregnancy week to week?

In general, most pregnant women have the following symptoms, although the severity or intensity with which they feel them varies. Here are the most common ones:

Absence of menstruation or amenorrhea

in women with regular cycles, approximately one week delay may indicate pregnancy. However, it is difficult to be sure that pregnancy exists, as menstruation may be delayed or not present for a month for another set of circumstances.

Nausea and vomiting

typically appear in the morning when waking up or after breakfast, and are due to hormonal alteration that occurs in the body after the embryo implants in the uterus.

PMS-like pain

It is common to feel pain similar to period pain. This usually occurs during the first few weeks of pregnancy, when the woman does not yet know she is pregnant.

Changes in the chest

there is an increase in size and sensitivity. The nipple areola may become darker and nipple pain may appear. It also increases blood supply so that the veins may be noted.

Skin spots

appear due to pregnancy hormones. They usually disappear after childbirth. It is known as chloasma.

Vaginal discharge

Vaginal secretions increase to prevent the baby from acquiring infections.

Increased urge to urinate

the uterus begins to grow during the first weeks of pregnancy, so it can put pressure on the bladder preventing it from filling up completely with urine. After the first few weeks, the uterus grows upward to occupy the pelvic cavity, releasing pressure from the bladder.

Fatigue and sleep

during the first weeks it is usually normal to want to sleep throughout the day and feel very tired. This usually refers to a few weeks, but there are cases in which it persists throughout the pregnancy.

Changes in taste and smell

Hormonal changes can lead to alterations in taste and smell. For this reason, it is normal that certain food cravings or even aversion or rejection towards others arise.

Dizziness and fainting

hormonal changes of progesterone and estrogens modify blood flow, causing more blood to flow to the uterus and slower flow, so it may occur that not enough blood reaches the brain for a few moments and fainting or dizziness occur.

Weight and volume increase

there is an increase of between 0.5 and 1.5kg per month, although it is very variable. The most significant increase occurs in the third trimester.

Stretch marks

are more frequent on the breasts, legs and abdomen. They are due to the excessive stretching of the skin that is produced by the increase of volume.

Cravings

may be because the body requires some vitamin or mineral, although there is no scientific explanation. It can also alter the appetite and you can go from being hungry to having nausea in a short time.
