Signs and symptoms of pregnancy can be disconcerting for some women. Tests pregnancy home are not always reliable and the time it takes can be misleading. Most women believe that once you are pregnant , do not bleed until birth, but that is not always the case. You may appear to have a period during pregnancy and have proof of pregnancy negative.
Home pregnancy tests
According to study of the “American Journal of Obstetrics and Gynecology” tests pregnancy home are very imprecise, reporting a large number of false positives and false negatives. In fact, only 1 in 18 home tests for pregnancy was able to detect a pregnancy at the time of a menstrual period. One option more reliable is that a doctor perform a blood test.
According to Toni Weschler, MPH, author of the bestselling book Taking Charge of Your Fertility (Taking control of your fertility), evidence of pregnancy should be taken at least 14 days after ovulation. While a fertilized egg implants in the uterine wall about seven to 10 days after ovulation – which means that a woman is pregnant – it’s hard to get a positive test result at first.
Some women may think they are having a period when they are actually experiencing spotting or implantation bleeding. The American Congress of Obstetricians and Gynecologists says that vaginal spotting may actually be quite common and most women who experience this still have healthy babies. According Weschler, implantation bleeding may resemble a very light period but the blood is more brown than red. The bleeding usually occurs between seven and 10 days after ovulation. Both can occur before a woman has a proof of pregnancy positive.
A pregnancy molar is a condition in which a mass of tissue, not an embryo implants and grows into the uterine wall. Molar pregnancies are caused by genetic mistake and should be surgically removed. Often the first symptom is vaginal bleeding. According to a 2010 study in the Singapore Medical Journal, the test results of pregnancy false negative are associated with pregnancy molar.
If a woman has her first positive tests for pregnancy and then has what appears to be a period with a negative result, is likely to have a miscarriage. Other warning signs include a jet of fluid from the vagina or expulsion of fetal tissue. The miscarriages are often genetic. A woman should consult your doctor or midwife immediately if you suspect a miscarriage because it may require surgery.
