Clinically, you can’t determine whether you’re pregnant simply by the early pregnancy reaction, and you need to go to the hospital for the final diagnosis. You can test the paper at home, and if you can’t, you can go to the hospital and get a blood test for HCG. HCG determines that the pregnancy is relatively early, earlier than the paper, and ultimately determines whether or not the pregnancy is really through the ultrasound, and if you do the ultrasound you can see the fetal sacs, and determine the situation of intrauterine pregnancy, you can be fully diagnosed, and this is the gold standard, and only the ultrasound to determine that the pregnancy can be diagnosed. Just have a simple early pregnancy reaction, can not determine the pregnancy, first of all to have a history of menopause, and then test paper, a deep and light or two bars, or go to the hospital blood test blood HCG to determine pregnancy. Generally in about six weeks after menopause can do ultrasound, the uterine cavity to see the fetal sac, can be diagnosed as intrauterine pregnancy. The development of the fetus is also subject to regular checkups.
