Generally speaking, it is normal for a woman’s menstrual cycle to move forward or backward by a week or so. However, if the menstrual cycle is usually regular and suddenly appears to be pushed back by seven days and accompanied by breast swelling and pain, for women who have sex, the first thing to consider is whether or not they are already pregnant. Therefore, it is recommended to buy early pregnancy test paper or pregnancy test immediately to test whether you are pregnant or not. If you are pregnant, first decide whether you want it or not. If you don’t want to, go to the gynecology department of the hospital in a week or so to check the ultrasound, see the intrauterine gestational sac after pedestrian abortion or medical abortion to terminate the pregnancy. If you want to have the baby, start taking folic acid immediately, and go to the gynecologist for blood HCG and progesterone to confirm the pregnancy.
