Using a home pregnancy test is one of the simple and highly accurate pregnancy testing methods used by women. However, in the process of reading the results, there are many situations that make women quite confused. If the fetus is not yet in the uterus, testing whether the test is up or not is one of many questions, especially for the women who are waiting for their baby to come home.
After fertilization, the egg moves to the uterus and starts its nesting process. About 6 - 9 days after successful fertilization, the egg implantation begins in the mother's uterus and it takes 7-10 days to complete.
However, depending on the condition of each pregnant mother, the time of pregnancy in the uterus will have a difference in time. On average, the implantation in the uterus takes about 9 days, but there are still cases that take 12-14 days for the fetus to enter the mother's uterus.
For mothers with irregular periods, it will be difficult to accurately determine the date of ovulation, so most doctors will calculate the fetal age based on the last menstrual date and this calculation will have an error of 1-2. week. So there will be cases that are counted as 4-5 weeks of pregnancy but still haven't entered the uterus.
Besides, during the process of moving through the fallopian tube to the uterus for implantation, the fetus can be "blocked" or "stray" and develop somewhere outside the mother's uterus.
The pregnancy test works by finding and detecting hCG, the hormone produced in the first part of conception. hCG aids in the formation of the placenta to transport nutrients from the mother's body to the fetus
Therefore, when the egg meets the sperm forming zygote, although the fetus has not yet moved into the uterus, if the woman uses the pregnancy test at the right time and the right way, it can still be up 2 bars. After 7-10 days of delay is an ideal time for mothers to use a pregnancy test to give the most accurate results.
Often there are no specific signs or symptoms of an unborn pregnancy. Detecting that the fetus has not entered the uterus usually requires an ultrasound and examination. However, when the fetus has entered the uterus, there will be signs such as:
Bleeding caused by an implantation of an egg in the uterus is also known as fetal bleeding. Bleeding from the fetus to the uterine wall is usually pale pink or browning
Cramps: Women can have mild cramps in the lower abdomen and back, which usually last 2-3 days.
Chest change: Chest tightness and pain are one of the earliest signs that appear when the fetus is in the uterus.
Sudden heat: A sudden heat that causes women to blush, feel hot and sweaty, which can last up to 50 minutes is one of the characteristic signs that occur during the day of implantation.
Except when the mother misses the date of her last menstrual period or the fetus is delayed for implantation due to the mother's condition, the woman should not be subjective when the test stick reaches 2 bars but the fetus has not entered the uterus. Maybe during the process of moving through the fallopian tube to the uterus for implantation, the fetus may be prevented because the mother experiences uterine abnormalities, such as: inflammation, ovarian deformity; chromosomal abnormalities ...
The uterus is the only place in the mother's body with enough space and nutrients for the formation and development of the fetus, so most ectopic pregnancies end in miscarriage or stillbirth. Therefore, in the first antenatal check-up, if the pregnancy has not yet been found in the uterus, the mother should follow up with the doctor's appointment and monitor the body's abnormalities such as abdominal pain, vaginal bleeding ... to have direction of timely handling.
