The fetus is growing rapidly, just as placenta. During the first weeks it looks like a thin shell with chorionic villi, but by the end of the term it’s already a thick (2.5 cm width, 480 g weight) mass. Do you feel its movements? Isn’t it lovely? At the first pregnancy women feel baby’s stir a little bit later.

Normal Pregnancy lasts about 40 weeks since the 1st day of your last menstrual cycle. Have you been already confused? Forget about calculations in your mind and notes in diaries – use our pregnancy calculator to find out the date of birth of your baby.

Using the Pregnancy Calculator helps to calculate the probable conception date, to estimate how long have you been pregnant, to know the fetal age and much more.

All you need is to enter the date of your last menstrual cycle and the amount of menstrual days in the data field, and push the button. On average a menstrual period lasts during 28 days, but it can differ from 22 to 44 days.
