How do you guess the first signs of pregnancy and what are the odds that you are pregnant? What role for pregnancy hormones at each stage of pregnancy? While some women discover their pregnancy after a routine examination by their gynecologist, others feel a real change in their body (due to the action of pregnancy hormones) from the first few weeks. What are the biological changes in your body and physiology when you are pregnant?
I feel then I’m… pregnant! The 9 symptoms that predict pregnancy
Signs of pregnancy more or less well felt by expectant mothers
Pregnancy symptoms, due to the secretion of pregnancy hormones, are unpleasantly felt by some pregnant women. However, they are harmless and do not pose any danger to the unborn baby. Legend has it that these signs that you are pregnant are a hint from the body to prevent the pregnant woman from exposing herself to unhealthy products such as cigarettes, alcohol, meat and fish that are not fresh, etc.
How to know if you are pregnant: the 9 first signs of pregnancy
Many symptoms assume that you are pregnant. These signs are mainly due to the pregnancy hormones produced at each stage. This can result in certain behaviors and habits, coupled with physical changes (swelling breasts, for example). It is important to specify that the signs that suppose that you are pregnant are not enough, they must be checked either by a blood test (to determine the HCG level) or by ultrasound.
Nausea: a distinctive symptom of pregnancy
Pregnancy nausea is an inconvenience experienced by many women in the first few weeks of pregnancy. They are due to the level of HCG (the pregnancy hormone) that increases when the woman becomes pregnant. The smell of coffee, which until then was your ally for a tonic awakening, torments your viscera. The fragrance of your favorite perfume generates a heart-warming feeling and in the city, the emanation of exhaust fumes makes your wanderings laborious. These signs may indicate that you are pregnant. However, they should under no circumstances be the only criterion for a possible pregnancy.
late or missed period, a good indicator of whether you are pregnant
You are regulated like music paper and for the first time, for no apparent reason, your periods do not appear. Doubt settles in and it is better to do a pregnancy test. Sometimes, traces of brown bleeding appear during the first week of pregnancy. Doctors call this phenomenon of implant bleeding.
Indeed, the egg settles in the uterus and while it makes its little place for itself, brown-colored bleeding can occur. However, it is preferable to inform your doctor.
During pregnancy, HCG (the pregnancy hormone) is the culprit in nipples, which change from their delicate pinkish color to a dark brown. Indeed, the action of HCG modifies the color of the vulva and areola. Also, small irregularities appear, it is the so-called Montgomery glands that stand out.
The sensation of breast swelling is also one of the distinctive signs and symptoms of early pregnancy. Immediately after fertilization, multiple hormonal changes follow, such as the enlarged mammary glands (located in the chest). That’s where a pregnant woman’s breasts get bigger. As a result, the pregnant woman feels a painful tightness in her chest.
Frequent need to urinate
This need manifests itself at night as well as during the day. The frequent urge to urinate occurs when the embryo is well “hooked” and produces human chorionic gonadotropin (HCG or beta HCG): the pregnancy hormone measured to confirm that you are pregnant.
Fatigue and dizziness
If you are pregnant, fatigue appears frequently. This feeling of fatigue that occurs in early pregnancy is due to the massive production of progesterone during the first few weeks of amenorrhea. This fatigue dissipates after about a dozen weeks. Some women have an unpleasant experience of dizziness, common symptoms of pregnancy. Indeed, this is a clear sign of pregnancy anemia due to iron deficiency. A diet rich in iron combined with a prescription should stop this dizziness.
You may find yourself having sudden and uncontrollable cravings. These cravings or desires are not the whims of a pregnant woman. And the saying “eating for two” is not always a reality. Although during pregnancy the mother-to-be needs vitamins and a balanced diet, this does not justify eating twice as much when you are pregnant.
At the beginning of pregnancy, many changes take place in the woman’s body. The stomach is at the center of many discomforts at this crucial time. Some will be prone to constipation, others to heartburn. The hard, swollen belly also causes sensations of heaviness. Don’t worry, everything will be fine after a few weeks. This pregnancy symptom is classic.
Mood swings, sensitivity at the surface of the skin
When you are pregnant, hormone production is at its peak at the beginning of pregnancy. The pregnant woman may feel invaded and overwhelmed with unwarranted sadness or, conversely, be taken with an outburst of euphoria. This may seem disturbing to those around you who will be affected by these changing moods. A little patience, experiencing pregnancy is not a trivial event. Carrying life, making room in your body to feel life blossom is a miracle that upsets and disorganizes a woman’s physiology.
A short primer on pregnancy hormones
When a woman gets pregnant, both her life and her body are shaken and undergo real changes. Most of these disruptions are due to the massive intervention of different pregnancy hormones.
The role of hormones at each stage of pregnancy, childbirth, and breastfeeding
From the first day of amenorrhea, the mother’s body is drowned in a shower of pregnancy hormones. At first, the Human Chorionic Gonade (HCG) increases dramatically. This sudden production causes several reactions in the body of the expectant mother. Then its production gradually dissipates. Progesterone and estrogen are secreted by the corpus luteum. Oxytocin is the attachment hormone, it is secreted at the time of delivery. At the end of pregnancy, prolactin also makes its mark. It is useful for triggering milk immediately after delivery.
Human Chorionic Gonade (HCG)
The level of HCG or Human Chorionic Gonade is the best-known pregnancy hormone. Symptomatic of pregnancy, it increases suddenly and dramatically after fertilization and gradually decreases over the weeks! It is this hormone in particular that is measured during a pregnancy test (in the urine or in the blood). Also, thanks to the production of HCG, the corpus luteum retains its action in the ovary. This leads to the production of estrogen and progesterone.
Progesterone and estrogen
Progesterone and estrogen are produced in the ovaries by the corpus luteum. These are the two hormones that allow the embryo to fix itself. Their role also allows the tissues of the uterus to change to adapt to the evolving size of the fetus.
Oxytocin or the primary love hormone
According to recent studies, this pregnancy hormone is secreted when the mother and baby are preparing for delivery. Oxytocin is the hormone of mother-infant attachment. It also has the function of triggering contractions.
Prolactin is the pregnancy hormone that produces breast milk. It is secreted at the time of delivery and is activated with each sucking of the baby.
