If you are not pregnant, only one line on the pregnancy test indicates that you are not pregnant, but it only indicates that you are not pregnant so far, or it may be that it is still early in the pregnancy test, so the (+) result is not yet detected. It is recommended that if you have not had your period for 1 week in this case, you can take another test using your morning urine to find out if you are pregnant. If there is still a line, it means that you are not pregnant and you can take progesterone orally to induce menstruation, and most of them will come 3-7 days after stopping the medication. In addition, if you do not have a period even after taking progesterone, it is possible that the menopause is caused by ovarian failure. It is recommended to have a blood test for sex hormone 6 if necessary to see if the follicle count is abnormally high. If ovarian failure is irreversible, you may not get your period in the future.
