If you are pregnant, you have to go to the hospital to have blood tests for HCG, estrogen and progesterone, as well as an ultrasound. The purpose of doing blood tests: on the one hand, it can confirm the diagnosis of pregnancy; on the other hand, through the increase in blood values and the specific results of the blood values, the doctor can determine the development of the embryo. If the estrogen and progesterone are too low, supplemental hormone therapy is also needed under the doctor’s supervision. The main purpose of the ultrasound is to rule out ectopic pregnancy, as well as to look at the development of the embryo in the uterus, whether or not the germ and heartbeat have appeared, and only those embryos that appear to have a germ and a heartbeat are viable. In the early stages of pregnancy, it is important to go to the hospital as soon as possible, and the doctor will give you the appropriate treatment, especially to rule out ectopic pregnancy.
