If your menstrual cycles have been regular up to now and there is a delay in your current cycle, the first thing to do is to rule out the possibility of pregnancy. There is a significant difference between a normal pregnancy and amenorrhea, and pregnancy can generally be detected through early pregnancy test strips if the menstrual cycle is irregular.

If the test strip is positive, it is generally considered likely that you are pregnant, and it is not a case of amenorrhea. If the test shows a negative result, then it is necessary to check the thickness of the endometrium. If the endometrium is thin, the likelihood of amenorrhea significantly increases.
