Early Signs of Pregnancy : First Trimester

Updated on October 14, 2011

Pregnancy is one of the most memorable stages of a woman's life. When everybody in the family learns that you are pregnant, all of them get so excited and wish you and your baby good health. They even want to extend their assistance on anything you need just to make sure you are in great condition and well taken cared of.

Starting a family life is a very exciting stage for most couples. Having a baby is the reality of their dreams to have that very special family they would love and care for their whole life. However, to some couples who are not ready yet, this stage is the turning point of their life. It is also the scariest, not knowing what is waiting for them in the future. Questions like, "Can I really take good care of my baby? Am I ready to become a parent? Will I and my partner be good and responsible parents to our child?" These are questions that we can't answer yet unless we are already in that situation.

The cases of teenage pregnancy is increasing yearly. Teens for example are not ready yet to be in this stage, however since it's already there, the best thing to do is to face the responsibility and be a good parent to your child. Your family will always be there to help you in any way they can.

The signs and symptoms of pregnancy maybe similar to premenstrual syndrome (PMS) which includes increase in appetite and craving for some foods, dizziness, bloating, abdominal cramps, increased fatigue and many more. These are very much similar to the early signs of pregnancy.


The most obvious sign of pregnancy is a missed period. When you had unprotected sex on your fertile days, the possibility of getting pregnant is high. In order to know whether you were fertile during the time you had sex, you can count from the first day of your last menstruation up to the day you had unprotected sex. A woman's ovulation period usually occurs on the 14th or 15th day since the first day of your last menstrual flow. However, certain factors like stress or sickness may affect your ovulation period.

In order to verify if you are pregnant, you can try an over-the-counter urine test or pregnancy test.This will identify if the hormone hCG or human chorionic gonadotropin is present in the urine which will indicate if you are pregnant or not.

At this stage, signs and symptoms similar to that of a woman's PMS will be experienced. These include: fatigue, frequent urination, pressure on the lower abdomen area, depression, food cravings, headaches, morning sickness, mood swings, excess saliva or a metal-like taste in the saliva. She may crave foods that she didn't used to eat before and may hate different scents of perfumes or even her bath soap. She can be so irritable at times and may cry a lot for no reason or extremely happy.

The baby at this time is about the size of a dime. He already has his eyes, head and mouth. His arms and legs are also growing and his lungs have started to form. His heart has also started to beat. At the end of the first month, the baby will be about half an inch long.

In the second month of pregnancy, all of the baby's organs are already present. Nausea usually begins to be experienced at this stage. Some women experiences morning sickness the whole day while others just in the morning. The change in hormones may also result to facial breakouts at this time. The baby in its second month approximately weighs an ounce and it's about an inch long.

It is recommended to start taking prenatal vitamins at this time. Supplements like calcium and folic acid are necessary in order to have a healthy growing baby and to prevent any birth defects. You are also recommended to have your first prenatal visit at this time..


On the third month of your pregnancy, your baby already has toes, fingers and soft nails. If you use a stethoscope, you can already hear his heartbeat. If you undergo an ultrasound examination, some parts of the baby are already visible like the hair, mouth, eyelids and eyelashes. At this stage, the baby can already detect light and possible dilation and constriction of the pupils may take place.

Some women experiences implantation bleeding or blood spotting at this stage. This means that the embryo already attaches itself on the uterine wall. However, not all women experiences this. In some cases though, some women thinks that this is a menstrual flow. However, as compared to a regular menstruation, the blood will be pinkish or brownish. This is usually followed by cramps.

As growth of the baby's organs takes place, you also experience gradual weight gain. You will also experience occasional back pain and achy legs because of the weakened stomach muscles. The baby also starts urinating at this time into the amniotic fluid.

A pregnant woman in the third month of pregnancy will also notice darkened areolas and increased tenderness of the breasts. She can also experience slight soreness on her breasts. The areola also increases in size and the nipples become tender with tiny little bumps on the breast (Montgomery's tubercles). One can also notice the appearance of stretch marks.

At the end of this stage, the baby will already weigh a little more than an ounce and is approximately 4 inches long.
