How do you know if your pregnant​?Generally, pregnancy can be determined by observing the cessation of menstruation and whether there are early pregnancy symptoms, combined with a test using a pregnancy test strip, a blood human chorionic gonadotropin (HCG) test, and an ultrasound examination of the uterus and its appendages.

If you usually have regular menstruation, had intercourse during ovulation without contraception, and now have a cessation of menstruation, morning sickness, fatigue, lethargy, loss of appetite, and other symptoms, as well as enlarged breasts and darker areolae, you should consider the possibility of pregnancy.

If you become pregnant after having sex during ovulation, the level of HCG in your blood will rise significantly about 8-10 days after intercourse. You can determine whether you are pregnant by taking a blood test for HCG.

If your period is delayed, you can use a home pregnancy test. If the result is strongly positive, it is more likely that you are pregnant.

If your period is delayed by more than 10 days, you can have an ultrasound to check whether a gestational sac has formed in the uterine cavity, and to observe the development of the fetus and the heartbeat of the heart tube.
