Becoming a mom is a great and wonderful experience. The human body goes through amazing changes to prepare to carry an embryo growing to a fetus to the end results of a beautiful baby. Pregnancy causes the body to change quickly where your regular clothes will not fit comfortably anymore. Buttons and zippers no longer close and waistbands hurt. Each pregnancy is different, whereby women can experience the need to be fitted for maternity clothing anywhere between the first trimester to the second trimester.
