Pregnancy Health: Top 7 Signs of a Healthy Pregnancy
Hormone Levels. Progesterone and estrogen, are two hormones that depict a healthy sign of pregnancy. A pregnant woman can produce upto 400 mg of progesterone, when compared to a healthy non-pregnant woman who produces around 20 mg of progesterone. These hormones set up the endometrium for implantation, hence keeping the woman away from menstruating, and keeping the uterus from contracting during the pregnancy.
On the other hand, estrogen's main job is to build tissue. It is estrogen that enables the uterus to amplify in size from approximately 60 grams before the pregnancy to about 1,200 at the later half of the pregnancy.
