What is the reason for the appearance of one deep and one shallow pregnancy test rod? How long can I use a pregnancy test stick during pregnancy
1. Testing with too little HCG during early pregnancy is not obvious
A household pregnancy test rod is used to determine pregnancy by testing the levels of chorionic gonadotropin (H) CG in urine. Women's ovulation date is usually twice in the middle of their menstrual cycle. For example, the menstrual cycle is 28 days, and the ovulation date may be around the 14th day. The implantation of fertilized eggs takes 7-10 days. After implantation, the placenta will form HCG, but the initial amount of HCG produced is relatively small, which takes at least a week to gradually increase. Roughly calculated, The pregnancy test will be more accurate after the next menstrual delay. If the pregnancy test rod is used too early, one deep and one shallow may occur.
2. Ectopic pregnancy leads to low HCG
Ectopic pregnancy refers to the abnormal pregnancy process in which a pregnant egg is implanted outside the uterine cavity, with the most common being tubal pregnancy. Under normal circumstances, a fertilized egg should be implanted into the inner wall of the uterus to form a placenta. However, if there is inflammation in or around the fallopian tube, which leads to unobstructed lumen and hinders the normal operation of the pregnant egg, it can stay, implant, and develop the fallopian tube. Excessive embryonic development can lead to fallopian tube rupture, manifested as severe abdominal pain and vaginal bleeding
After general pregnancy, the secretion of HCG will rapidly increase. If β- The increase in HCG every two days is greater than 66%, which can be diagnosed as intrauterine pregnancy; If the increase is less than 66%, there is a high likelihood of ectopic or intrauterine pregnancy developing poorly. If there is a delay in menstruation, the pregnancy test stick will continue to show a deep or shallow phenomenon., Go to ultrasound as soon as possible to check if the fetal development is normal.
3. Other reasons for the depth and depth of the pregnancy test rod
During ovulation, women's HCG and LH levels will reach their peak and return to normal levels after ovulation. However, before the next menstrual period, these two values will slightly increase. If the pregnancy test rod used is too sensitive, shallow detection lines are easy to display.
The recommended way to use pregnancy paper correctly is to use the first urine test in the morning as much as possible, as hormone levels are most easily detected at this time. For example, not urinating in the morning or drinking too much water at night., So at least ensure that urine in the bladder takes at least four hours to be detected. Otherwise, it is easy to cause the depth of the pregnancy test paper.
How long can a pregnancy test stick detect pregnancy?
It only takes 6 days at the earliest to check if the pregnancy rod is pregnant. Of course, if you want to be more accurate, wait 11 days later, it will be more accurate at that time.
After 1 minute (up to 30 seconds), the pregnancy (positive) result can be determined. It refers to the two clear lines displayed after 1 minute during the test, which display the pregnancy (positive) result without waiting for 3 minutes to determine.
