The menstruation proves that there is no pregnancy, so the test does not show pregnancy. If women who usually have regular menstrual cycle, the postponement of menstruation for more than one week indicates the possibility of pregnancy, and the early pregnancy test paper can be used to detect whether it is pregnancy. If bleeding occurs after the postponement of menstruation and the amount of bleeding is relatively small, it may be due to bleeding from the bed after pregnancy, pre-eclampsia or ectopic pregnancy performance. You can use the test paper to detect pregnancy and the bleeding is not menstruation. If the bleeding is like the usual amount of menstruation within one week of the postponement of menstruation, it should be normal to have menstruation, just a postponement of menstruation. The reason for a delayed period once in a while may be related to mental tension or environmental changes. Some people who are eager to get pregnant sometimes have a delayed period and experience false pregnancy reactions such as nausea and vomiting.
