If your period is delayed for 15 days or 15 days after intercourse, you can check if you are pregnant by using pregnancy test or blood chorionic gonadotropin. Two bars on the pregnancy test paper and chorionic gonadotropin greater than 10 mIU/ml indicate pregnancy, and an ultrasound can be used to further confirm whether the pregnancy is intrauterine after 40 days of menopause. If your period is not regular and ovulation is delayed, you may not be able to detect it, and you need to prolong the test, and if your period is not coming for a long time, you need to repeat the test. Usually pay attention to rest, pay attention to keep warm, eat a light diet, avoid spicy and stimulating food, do not stay up late, relax your mood. Women with regular menstrual cycles can be tested for pregnancy if they have stopped menstruating for more than a week.
