Pregnancy typically lasts 40 weeks, divided into first, second, and third trimesters. Different symptoms and physical developments characterize each stage. The beginning of pregnancy iscalculatedfrom the first day of the last menstrual period (LMP) (1).

After every menstrual cycle, a woman’s body starts preparing for pregnancy. Since knowing the exact date of conception is difficult, doctors refer to the first day of the last menstrual cycle as the start of the pregnancy (2).Ovulation begins after about 12-14 days of LMP, as the egg is released.This is when conception or fertilization is likely to occur if you have unprotected intercourse (3).

In this post, you might learn about the second week of pregnancy, including the symptoms and the measures to follow for baby development.

What Happens At Two Weeks Of Pregnancy?

The first day of the reproductive cycle begins as soon as the last menstrual period ends.At the beginning of the second week, the dominant follicle containing the egg releases an increased amount ofestrogenⁱXA sex hormone responsible for the development of female sexual characteristics, stimulating thepituitary glandⁱXA tiny pea-sized gland situated behind the bridge of the nose and controls other hormone glands in the bodyto release theluteinizing hormoneⁱXHormone that stimulates ovulation in women and causes testicles to make testosterone(LH) by day 12.Around day 13, a surge in the LH levels causes the follicles to burst open and release the egg. By day 14, fertilization occurs in thefallopian tubeⁱXPair of tubes that carry eggs from ovaries to the uterus in womenfollowed byimplantationⁱXThe process of the embryo finding its way through the fallopian tubes and into the uterus, where it attaches to the wallsin the uterus about six days after fertilization (3) (4).

At two weeks pregnant, thebabyis made of only a few cells, andfetal developmentmay not be detectable through anultrasound．The mother’s belly generally does not appear bloated and there are no distinguishable pregnancy symptoms during the second week. It could be around the third orfourth weekwhen the typical pregnancy symptoms, such as missed periods, nausea, and morning sickness, start to manifest as the embryo develops.

What Are The Signs And Symptoms At 2nd Week Pregnancy?

Since fertilization only occurs by the end of the 2nd week, you may not observe any symptoms. However, some women might experience (5):

• Discharge of a fine mucus layer, with an appearance similar to that of an egg yolk.
• Sudden lowerabdominal painon either side, indicating release of the egg.

• An increase in temperature, which can occur after ovulation.

Other possible signs and symptoms might include:

• Tender and sore breasts

• Randommood swings
• Frequent urination
• Unusual and constant tiredness
• Constantbloating or gas

These symptoms during the second week of your menstrual cycle may indicate the beginning of your gestation period although they are not very reliable at this stage.

Can A Pregnancy Test Give A Positive Result At Two Weeks Of Pregnancy?

A pregnancy test is based on detecting the levels ofhuman chorionic gonadotropin hormoneⁱXProduced in the placenta, the hCG hormone is vital in establishing and maintaining early pregnancy(hCG)．这是特殊的细胞称为syncytiot发布的rophoblast around ten days post-conception until the placenta is fully formed later in thefirst trimester, which then takes over this function fully. Hence, an accurate pregnancy test at two weeks of pregnancy may not be possible.

You can expect to have a positive pregnancy test result after two weeks of fertilization, i.e., during the fourth week of pregnancy when there is an increased hCG concentration in the blood and urine. Apregnancy testcan be carried out through pregnancy test kits or a blood test. You can use the test kit two weeks after conception for an accurate result (6).

What To Do At Two Weeks Of Pregnancy?

If you are entering the ovulation phase and are planning to get pregnant, you may try the following for pregnancy (2) (5).

• Keep track of ovulation:You must plan according to your ovulation cycle if you plan to have a baby. For pregnancy to occur, sperm should fertilize the egg when it reaches the fallopian tube.Knowing the time of ovulation or the fertility window can help you plan your intercourse timing and increase your chances of achieving a successful pregnancy.You can use an ovulation kit that measures theurinelevel of LH, responsible for the release of egg from the follicle.

• Change to a better lifestyle:For better prenatal care try to have a healthier lifestyle with regular exercise and awell-balanced diet．A change in your otherwise lazy or hectic day-to-day life can provide a healthier environment for your baby.

• Increase vitamin intake:Increase the intake of prenatal vitamins after consultation with healthcare providers.

This is particularly important for those who have diabetes mellitus.

• Avoid toxic substances:Do not consume substances that can harm not only your health but also your expecting baby by increasing the risks for a miscarriage, stillbirth, and preterm labor. These can include tobacco, alcohol, recreational drugs, or caffeine.
