First Trimester Pregnancy | Sign and Symptoms of Pregnancy |

I'm going to discuss the sign and symptoms of pregnancy. The pregnancy period starts from the first day of the last menstrual period, and when we are calculating from that period, that is called menstruation age or gestational age, and it is rough of about nine months and 7 days or you can say that 280 days or 40 weeks of gestation. So, this whole pregnancy period is divided into three trimesters that trimester means three months tri means three. So, how many trimesters are there, that is three trimesters are there. So the first trimester starts from the first day of the last menstrual period till 12 weeks, and, the second trimester belongs to 13 to 28 weeks of gestation, and the last or third trimester starts from 29 weeks of gestation till 40 weeks of gestation so in this article, will discuss what all signs and symptoms the woman may have during the first trimester.

So in the first trimester,

What all symptoms the woman may have that usually she felt, and what all signs are there that the examiner observes?

Here, first, we talk about the symptoms.

The first symptom that the woman usually complains of is amenorrhea that is the absence of menstruation because, after a consecutive, regular menstrual cycle, she felt suddenly there is no menstruation, menstruation is absent. So, this is the first sign or symptom that usually the woman felt.

The second symptom that she felt is fatigue that is tiredness. So after taking a good amount of rest, also she won't feel better or active. So, the second symptom that the woman usually complains of that is fatigue or tiredness.

Then the third symptom is morning sickness that is nausea and vomiting. Usually, it is termed as morning sickness, but it can appear in any period in a day that it could be found in an afternoon or the evening. So morning sickness that she may have nausea and vomiting and why it is appearing because there is a trophoblastic cell after implantation. There is a trophoblastic cell that releases at hCG (Human Chorionic Gonadotropin) to maintain this pregnancy. So this hCG is responsible for this morning sickness, okay, that all we'll discuss in detail are physiological changes. And this morning sickness usually remains in the first trimester only and that could subside in subsequent trimesters.

Then the fourth symptom that the women usually have is the frequency of micturition. So, a woman is usually urging for more and more voiding, there are many reasons like there is a change in osmoregulation because there are many maternal adaptations that are going on during this pregnancy period. So this osmoregulation change causes thirst in a woman and this excessive thirst may lead to the excessive drinking of water and that may ultimately lead to polyuria. So this could be the one reason, and along with that what happened?

The position of the uterus is anteverted and once this anteverted uterus is growing more and more with the subsequent weeks, what happened?

That enlarging uterus compresses the anteriorly situated bladder because we know that in the anterior aspect there is a bladder, so with this growing uterus the bladder is compressing and that may lead to more urging for voiding and along with that, the woman may have some breast issues and breast difficulties, discomforts like she may feel a feeling of fullness or many pricking sensations.

So, these are the symptoms that usually women complain that may have amenorrhea fatigue, frequency of micturition, morning sickness, and breast discomfort.


What all signs are there that the examiner could find during this first trimester?

Firstly, what all breast changes are there? So, under the influence of the hormone, what happened?

There is a darker pigmented area around the nipple and the areola. So there is a dark pigmentation and there are some sebaceous glands that lie underneath this areola part which are not visible in the non-pregnant state, but under the influence of hormones what happened to these sebaceous glands become hypertrophied and they are visible as a small nodule over the areola. And these are called Montgomery tubercles.

So, especially It is evident in a primigravida woman who doesn't breastfeed her baby previously. So Montgomery's tubercle could be evident, as well as the darker pigmented area around the nipple and areola could be found in the first trimester. And along with that, the thick colostrum could be squeezed out during the first trimester as early as 12 weeks of gestation.

So these all are the signs which we can find during the first trimester.

If we are observing the size, shape, and consistency of the uterus, and the enlarging property of the uterus, the uterus remains the pelvic organ in the first trimester. So, we cannot palpate in the abdominal area because it looks like a suprapubic bulge because the height of the uterus till 12 weeks remain in the pelvic region only okay in the pelvic that is in the pelvic cavity only. So, it will not appear as a bulging in the abdominal region. Therefore, it looked like a suprapubic bulge till 12 weeks of gestation.

Now, there are many signs like Jacquemier's sign, or you can say Chadwick's sign. This is the sign, in which the vestibule we already discussed in the external genital region, what is vestibule? So, in the vestibule, there is discoloration of the vestibule as well as the anterior vaginal wall. There is a dusky hue appearance of these two structures, or you can say there is a discoloration, the bluish discoloration of a vestibule and anterior vaginal wall and that could be evident as early as eight weeks of gestation. So that is called Jacquemier's sign or Chadwick sign.

Another sign is Goodell's sign, that is the softening of the cervix and how we can find out that the cervix is so how much what is the consistency of the softness that initially in the non-pregnant state, it feels like a tip of the nose, in the pregnant state it is feeling like a lip of mouth so that much cervix is softened. So the Goodell's sign is the softening of the cervix and that could be evident as early as six weeks.

The next sign is the Osiander's sign, which we know that there is a cleft that is forming because of the protrusion of the cervix into the vagina. So at the topmost corner of the vagina, there are the four fornices anterior, posterior, and two lateral fornices. When we do the bimanual examination, we felt that is pulsation, where? at the lateral fornices. So the pulsation felt through these lateral fornices could be evident as early as eight weeks and that is to be called Osiander's sign.

And the next sign is the Pickaxe's sign. So what it is? Usually what happened once the blastocyst is implanted in the uppermost part of the uterus, the only uppermost and the slight lateral part is only enlarging remaining whole part is remain as it is. So, with this lateral implantation, the uterus is growing laterally, there is an asymmetrical enlargement of the uterus because the remaining non-involved area of the uterus remains as it is.

So because of that, there is an asymmetrical enlargement the other part remains as it is and that is called the pickaxe's sign. But as the fetus grows more and more, this restores the normal symmetrical enlargement. With the advancing pregnancy, what happened, the uterus grows more and more So initially, the size of the uterus at six weeks is about hen's egg, but as it becomes grow more, at eight weeks, it becomes cricket ball, and as it becomes grow more, by 12 weeks, it looks like a fetal head or globular in shape.

Now, another sign is Palmer's sign, and what it is, is that there could be a regular rhythmic uterine contraction and this could be felt through bimanual examination. But as the pregnancy advances, this regular rhythmic contraction becomes just disappears because the uterus remains in a quiescent phase in a quiet mode. So, we cannot feel any rhythmic contraction, it could be evident as early as four to eight weeks of gestation only. So, this is called the Palmer sign where the regular rhythmic uterine contraction could be felt through bimanual examination.

And another sign is the Hegar's sign, and what it is, in this sign it is evident that the upper part of the uterus is growing more and more with the advancing pregnancy. And comparatively the lower pole of the uterus remain soft and empty and how it could be evident. So, this could be evident by bimanual examination where the examiner can place his or her hand in the anterior fornix and another abdominal hand could be placed on the back of the body of the uterus.

Therefore, he or she may observe that both the fingers may oppose each other, where it is opposing that in the lower part of the uterus, which is soft and empty, but the upper part where the fetus is growing, that is globular and it is enlarging and relatively the lower pole remain empty or soft. So that is called the Hegar's sign.

Hence, here in this article, we have seen what are the signs and symptoms the woman may have during the first trimester.

Thank you.
