Has anyone seen this new program on the Discover Health Channel, I knew he was pregnant.Well apparently this has happened to many women, because theres always a new episode. It's hard for me to believe that someone could not know that was prego, especially when I see all my prego friends comments on their blogs and Facebook about how uncomfortable they are and how much can I expect there is no baby in her arms, and have the prepregnancy bodies back. But nonetheless, it happens. Here are some reasons why: We've all heard stories about women not knowing they were carrying a child until very late in pregnancy ... or even labor begins in But how can this be Besides the obvious reason (denial!) A number of factors that may contribute to pregnancy of the quot; sorpresaquot; phenomenon: 10. Fetus is small, inactive, and / or carried to the back of womb.Believe or not, sometimes babies just do not make a stir in the womb. Also, babies of some women rest, of course, to the back of the matrix, so that the movement and kicks are not easily detected from outside the body of the mother. Many women believe that fetal movements are irregular or strong digestive activity! 9. Recent previous childbirth.Many still believe women can not get pregnant after childbirth or while breastfeeding. In addition, menstrual cycles may be irregular, and women can continue to bleed from the vagina for several weeks after delivery. The truth is that some women ovulate and can become pregnant within the first days after delivery! 8. Dieting.Women assets that are very religious and weight control can crank up your workout routine and / or start a diet when they become aware of weight gain. Because of this, you do not gain weight as your pregnancy progresses.7. Stress.Stressful jobs, family and personal life to contribute to irregular periods, and can women do not pay attention to their menstrual cycle, or to join the absence of menstruation stress.6. Fetus is mistaken for a tumor or cyst.In some cases, especially when a woman has a history of endometriosis, cysts, fibroids or other tumors of the reproductive system, a fetus may be mistaken for a new or recurrent tumor.5. Obesity.Carrying a lot of excess weight can hide perfectly quot; beb�quot bump;. Depending on how a woman's body deposits fat, may have seemed quot; embarazadaquot a bit, in the past, and neither she nor others notice the extra bulk of a fetus.4. Inaccurate use of birth control.Many women are confident that it could not be pregnant because they use contraception. However, all contraceptive methods have a failure rate and the possibility of pregnancy increases exponentially if contraceptive methods are not used exactly as shown: missing pills, expired condoms, and similar problems may lead to a surprise pregnancy in women who are sure they are in the clear.3. Advance bleeding.Some women still bleeding as a period during pregnancy, may be lighter or irregular, or even coinciding with the usual time of women quot; the mesquot;. These pseudoperiods can be enough to convince a woman that is not pregnant.2. Test.Home home pregnancy negative pregnancy tests are not foolproof. Whether taken or read incorrectly, or simply give a false reading, once a woman has tested negative for pregnancy at home, just a general rule, out.1. History of irregular cycles and / or infertility.Not to get pregnant in the past, a history of missing or irregular periods, and / or be close to the menopause a woman can fool into thinking that it could not be pregnant. The truth is that, unless a method of birth control is used every time a woman has sex, she can get pregnant! Now after reading all that, I will share what I learned in the series. Almost all the women that birth control function and use for some reason necessitates the use of antibiotics decreases the effectiveness of BC during use. Interesting ... Do not you br br
