Theoretically speaking, 4 weeks pregnancy marks definite hormonal changes. You might now experience early pregnancy symptoms including fatigue, swollen breasts, bloating and frequent urination.
The pregnancy fourth week i.e. the week just before your next menstrual cycle is the time when implantation occurs. During implantation, the baby searches for a comfortable place in the uterus and implants i.e. get settled in for the rest of the pregnancy time. The cells now begin to divide into two groups viz., the group that forms placenta and the other group that forms the baby.
The chorionic villi are formed, the placenta that is supposed to take care of child till birth is appearing and most importantly, the little one's heart is beginning to beat. In the true sense this is the phase when life is actually generated. From the initial cells to the present blurred images that begin to form, there has been a major movement towards creating life.
By now you must be very anxious to find out if the pregnancy is confirmed. The wait game to get concrete results by an early pregnancy test however could stretch forward to the fifth week. Though a urine pregnancy test can be undertaken during the fourth week, it might or might not show accurate results. It is a home pregnancy test also known as ept pregnancy test (early home pregnancy test) that checks for the special pregnancy hormone known as HCG (human Chorionic Gonadotrophin) hormone required for the confirmation of pregnancy can be conducted.
