Menstruation is delayed for a week and the pregnancy test stick is dark and light

Generally, women's menstrual cycle is about 28-30 days. It is normal to be early or delayed by about 7 days. However, if the menstruation is delayed by 7 days and one line is dark and the other is light on the pregnancy test stick, does it mean that you are pregnant? In order to let all female friends have a certain understanding of the reasons for delayed menstruation and how to check the results of pregnancy test sticks, the editor will explain it to you in detail below.

What's the matter with one dark and one light pregnancy test stick when menstruation is delayed for a week?

Menstruation is delayed, and the pregnancy test stick shows one dark and one light. At this stage, it indicates that the early pregnancy test paper is weakly positive. Because the blood hcg level is low at this time, the color of the pregnancy test stick is not obvious, which is called weak positive. Generally speaking, if there are no special discomforts such as abdominal pain and vaginal bleeding, you can go to the outpatient gynecology department about 40 days after menstruation to have blood HCG and progesterone level tests; if necessary, a gynecological uterine adnexal ultrasound examination can be done to further confirm the location of pregnancy and the time of menstruation, so as to facilitate the next step of treatment.

1. Only one comparison line appears in the information window of the pregnancy test stick, indicating that you are not pregnant.

2. Two lines appear in the information window of the pregnancy test stick, that is, both the comparison line and the detection line are colored, and the detection line is obviously clear, indicating that the woman is already pregnant.

3. If no contrast line appears in the information window within 5 minutes after using the pregnancy test stick, it means that the test is invalid or unsuccessful.

4. The information window of the pregnancy test stick shows one dark and one light. If the contrast line is obviously clear and the test line is very light, it means that you may be pregnant, but it is uncertain. In this case, it is recommended to use a new pregnancy test stick to collect morning urine and test again the next day. You can repeat it several times to confirm.

Reasons for delayed menstruation

1. Pregnancy. If you experience symptoms such as nausea, vomiting, and breast pain after your period is delayed for 7 days, you can use a pregnancy test stick to conduct a urine test to determine whether you are pregnant.

2. Side effects of drugs. If endocrine imbalance occurs after long-term use of emergency contraception, menstruation may be delayed by 7 days.

3. Caused by surgical treatment. For example, intrauterine surgical treatment may cause cervical adhesions, leading to menstrual blood stasis, thereby delaying menstruation.

4. Others. Psychological disorders such as anxiety, too much pressure, changes in the natural environment, and some endocrine-affecting diseases can all cause delayed menstruation.

How many days of delayed menstruation can I test for pregnancy

Generally speaking, male sperm can reach the female's bilateral fallopian tubes within 1-2 days after intercourse, and tightly combine with the female's discharged egg cells in the bilateral fallopian tubes to produce sperm-egg fusion. The combination of sperm and egg is promoted by the microvilli in the fallopian tubes on both sides, and it will take about 6-7 days to reach the uterus. If the conditions are met, the embryo can implant on the uterine wall. Embryo implantation is a sign that a woman is pregnant. Therefore, it takes at least 6 or 7 days from fertilization to pregnancy. Therefore, 7 days after the menstruation is delayed, you can use the pregnancy test stick to use morning urine to test for pregnancy.

The above is the editor's introduction to the deep and shallow pregnancy test sticks for 7 days of delayed menstruation. I hope you have already had a certain understanding of it. When using the pregnancy test stick to test pregnancy, you must first read the instruction manual carefully and use the appropriate steps and specific methods. This can improve the accuracy of the pregnancy test stick. However, if you are still uncertain about the result, the editor recommends going to the hospital for regular examination and diagnosis in time.
