I got my period 4 days before my period and found two lines.

Many women will have some obvious symptoms before and after menstruation, but it is also possible that some women take a pregnancy test after having sex when it happens to be close to their menstrual period. For example, some women may show two lines on a pregnancy test just four days before their period. This may be related to the timing of the woman's sexual intercourse and further examination is needed. So is it normal to have two lines 4 days before my period?

1. If the patient is 4 days away from her period and there are two bars on the urine pregnancy test, it means it is positive and the patient can basically be sure of being pregnant. Urine pregnancy tests have a certain false positive rate, so patients are advised to change to another brand of test strips and test again with morning urine the next day. If there are still two bars, it proves that the patient is pregnant or the patient can go directly to the hospital to check the blood HCG. Blood HCG can more accurately determine whether the patient is pregnant. However, whether it is through urine testing or blood testing, it can only be determined that the patient is pregnant, and there is no way to determine whether it is an intrauterine or extrauterine pregnancy. If the patient currently has no abnormal bleeding or abdominal pain, it is recommended that the patient have a color Doppler ultrasound examination after one week to determine whether it is an intrauterine or ectopic pregnancy. If you have abdominal pain and abnormal bleeding, go to the hospital immediately to rule out the possibility of ectopic pregnancy.

2. If conception occurs during intercourse, blood tests can be done around the 10th day after intercourse to check the human chorionic gonadotropin level. The value will be higher than normal. If menstruation comes 4 days before conception, it can be found that the human chorionic gonadotropin level is higher than normal, confirming pregnancy. Because the conception time is short and the blood human chorionic gonadotropin value is very low, it is recommended to observe dynamically to understand the increase of blood human chorionic gonadotropin, and to do a color Doppler ultrasound examination to clarify the location and development of the gestational sac. If you do not have any discomfort symptoms such as lower back pain, abdominal pain, vaginal bleeding, etc., it is recommended to go to the hospital for a color Doppler ultrasound examination around 6-7 weeks of pregnancy, and repeat the examination if necessary. If you feel unwell, go to the hospital immediately.

3. Normal phenomenon. Because under normal circumstances, the earliest time that pregnancy can be detected clinically is 30 or 31 days after menstruation through blood HCG test. If you are found to be pregnant even though you haven't had your period for four days, it is recommended that you carefully review whether your last menstruation was normal, especially whether the amount and timing of your menstruation are different from previous menstruations. In this case, most people think that the woman was already pregnant last month but it was not discovered. It is recommended to have a B-ultrasound examination, the main purpose of which is to understand whether the size of the gestational sac is consistent with the number of days of amenorrhea, and then to calculate the approximate time of pregnancy based on the results of the B-ultrasound examination.
