Doubtful - a different kind of subjective feelings and purely external evidence: the whims of taste and smell, drowsiness, mild fatigue, skin pigmentation on the face, the white line of the abdomen, nipples, external genitalia. It likely features include: cessation of menstruation, breast enlargement and the emergence of colostrum during extrusion of the nipples, loosening and cyanosis vulval vestibule, of the vagina and cervix, and changing the shape of the uterine consistency, increasing its size, the positive biological response to pregnancy. Detection is performed by interviewing, palpation, inspection of the external genitalia and vaginal mucosa by means of mirrors and vaginal examination.

In the second half of pregnancy, there are signs, certainly indicative of the presence of the fetus in the uterus. These include: fetal movements felt by hand, listening to the heartbeat probing head, buttocks, legs, handles the data of X-ray studies, elektrofonokardiografii, ultrasound. delivery day can be calculated by adding 280 days to the date of the first day of the last menstrual period; or count from the first day of the last menstrual period 3 months ago and added to the resulting number of 7 days (Negele formula).
