Nowadays, when women suspect that they are pregnant, they usually choose early pregnancy test strips for testing. As long as there is a delay in menstruation, the accuracy of early pregnancy test strips is still quite high. However, early pregnancy test strips also have certain drawbacks, as they are not 100% accurate, especially in the early stages of pregnancy. Is it accurate to have a negative urine test in the afternoon after 23 days of sexual intercourse?

Generally speaking, delaying menstruation by 7 to 10 days can detect whether a woman is pregnant. As long as the fetus is not released, it can be detected through early pregnancy test strips, but it is not 100% accurate. The longer the pregnancy, the more accurate the test results will be. If the examination shows pregnancy, it is recommended that you go to the hospital for B-ultrasound examination around 40 days of pregnancy. If there is a gestational sac, it is an intrauterine pregnancy; If you are not pregnant during the examination, you can relax and wait a few more days to see it.
What are the symptoms of early pregnancy
1. Menstruation hasn't arrived yet
If your menstrual cycle has always been regular but does not arrive on time this time, there is a high possibility of pregnancy, so it is necessary to undergo early pregnancy testing. But if your menstrual cycle is irregular, or if you don't remember your menstrual cycle, early pregnancy symptoms such as nausea, chest tenderness, and frequent use of the bathroom may indicate that you are pregnant before you realize that your menstrual cycle hasn't arrived.
2. High basal body temperature
In the early stages of pregnancy, the physical symptoms are not obvious, but the basal body temperature remains high. If you record your basal body temperature and find that it has been in a high temperature state for 18 consecutive days, you are likely to be pregnant.
3. Breast enlargement and sensitivity
One of the early signs of pregnancy is breast sensitivity and tenderness, which is caused by an increase in your hormone levels. This feeling of bloating and pain is very similar to what you feel before your menstrual period, just stronger.
4. Tired
Do you suddenly feel tired, even exhausted? No one knows for sure what causes fatigue in early pregnancy, but rapidly increasing levels of progesterone (also known as progesterone) may make you feel particularly tired.
After 23 days of sexual intercourse, the urine test was negative in the afternoon. If someone remains skeptical about this result, they can directly go to the hospital for a blood routine test to check the concentration of HCG in their blood. Generally speaking, after seven days of sexual intercourse, it can still be detected through early pregnancy test paper, but the longer the time, the higher the accuracy. This is something that everyone must remember.
