Pregnant belly shape and fetal relevant
Army Li, deputy director of Chaoyang Hospital, said the shape of the pregnant belly,http://propertychecksofmaine.com/cache/yxvwmesfct.html, and the baby's gender is no relationship. Why pregnant belly shape will be different? On the one hand, and the baby's fetal position may be, the baby's size has a relationship.
In addition, pregnant belly shape with their abdominal muscles are. For example,http://redboxphoto.net/wp-cache/upuucaaxhc.html, some pregnant belly shape than the tip, probably due to perennial exercise, abdominal muscles weak; If the abdominal muscles strong, the stomach may be relatively smooth.
In addition, the shape of the stomach and pregnant women are also the usual walking posture, etc. have a certain relationship.
Rumors 2 see tastes "sour spicy men and women."

Female baby: Pregnant women prefer spicy flavors,http://blog.elitemate.com/new_blog/no,status=no,menubar=no,scrollbars=yes,resizable=yes,width=780,height=550.
Taste from the "stomach memory"
Army Korea said that this "sour spicy men and women," the legend is very common, but not scientific. Pregnant women due to pregnancy reaction after pregnancy, hormone levels change, resulting in changes in taste, diet changes are possible.
Some pregnant women may be due to pregnancy, poor appetite,http://www.brianleemarketing.com/cache/sdrwqwqpnu.html, things like spicy, intense flavor diet helps pregnant women to effectively stimulate the appetite. In addition, pregnant women resist certain foods may stem from "the memory of the stomach," such as had eaten something,http://www.grobelny-pleszew.com.pl/table/wjuqwfzhou.html, cause uncomfortable reactions. But certainly can not draw "sour spicy male female" rule.

This argument is also very scientific. Army Korea introduced first,http://ohh.sisos.co.jp/cgi-bin/openhh/jsearch.cgi, fetal movement speed sooner or later, to a certain extent dependent on the subjective perception of pregnant women.
In addition, fetal situation how,http://lyb-ems.com/wp-cache/whlzgvzeue.html, and every pregnant woman's abdominal wall will have a different relationship Bohou, if maternal abdominal wall is thick,http://www.clarityenglish.com/englishonline/index.php?item/create_form/1, probably late fetal movement can feel the baby in the womb; rather thin abdominal wall early in pregnant women might feel.

Army Li,http://www.erta.at/data/xdxzduajuy.html, deputy director of Chaoyang Hospital introduction, many pregnant women feel that their skin after pregnancy will be some change, but not directly come because of "ugly become beautiful" is a boy or a girl conclusions.
Skin changes are related to changes in hormonal and pregnant women, but the specific kind of change will happen, but also the skin's own skin and pregnant women, such as the secretion of oil a relationship. For example, some pregnant women,http://www.hotel-amira.at/cache/evioxrvsdn.html, coarse skin follicles, after pregnancy may increase oil secretion, so they grow up acne.

Male baby: fetal heart rate is slower, about 140.
Female baby: fetal heart rate faster,http://als-net.com/cgi-bin/keijiban/als-keijiban.cgi, 150 or so.

First, fetal heart rate between 120-160 are within the normal range, as long as this range in the beat,http://propertychecksofmaine.com/cache/ydkrpqhyuy.html, the baby is normal. In addition, even with a baby under different state measurement,http://www.aleksil.com/cache/kkyslstiux.html, heart rate may not be the same.
