There are many symptoms that appear in the early stages of pregnancy. The first one is menopause, which means that your period is usually regular and does not come when it should, so you need to be alert for pregnancy. Then you may experience frequent urination, which is due to the enlargement of the uterus after pregnancy, which presses on the bladder in front. In addition, in the early stages of pregnancy, the sperm meets the egg to form a fertilized egg, which lays on the endometrium and the trophoblast secretes chorionic gonadotropin. The ovaries secrete estrogen, progesterone, and placental lactogen, and under the influence of these hormones, the breasts develop and become swollen and painful at this time. In addition, under the influence of chorionic gonadotropin levels, pregnant women may experience pregnancy reactions such as nausea, vomiting, aversion to grease and food, and some women may also experience fatigue and drowsiness. It should be noted that not all women will experience vomiting reactions. Depending on the individual’s physical condition and the influence of estrogen in the body, those with mild symptoms will only show a loss of appetite and occasional nausea, while those with obvious symptoms will have severe vomiting. In the early stage of pregnancy, you should pay attention to rest, have regular maternity checkups, keep your mood relaxed, and forbid sexual intercourse.
