Especially annoying if you have problems getting pregnant or on the contrary that you fear a unplanned pregnancythe announcement of a Pregnancy test false positive can be devastating. Because when women who don’t want a child right away don’t turn out to be pregnant while they wait to find out the truth, they can be in intense psychological distress. For those who dream of becoming a mother, hope is crumbling.
Although relatively rare the false positive can happen for many reasons. However, you should know that it is only possible to get a false positive result from a pregnancy test urine, sold in pharmacies and supermarkets. That blood tests they are infallible.
A recent pregnancy can make the test positive
Whether carried to term or terminated by miscarriage or voluntary termination, pregnancy leaves trace amounts of hCG (human chorionic gonadotropin). These traces remain in the body for up to 6 weeks after a miscarriage and several months after pregnancy. In addition, by doing it too quickly, it is possible to get a positive pregnancy test afterwards, when in reality there is no longer any pregnancy or no effective pregnancy in the body. However, it is common for a miscarriage to occur even before a woman realizes it was her pregnant.

These situations are not considered false alarms
Sometimes the pregnancy test shows a positive result, but you are not actually pregnant. And yet, strictly speaking, he made no mistake. There are several explanations for this.

The urine test can detect an increase in hCG hormone levels and the test result is therefore positive.
This also applies to the case pregnancy molar toothwhat a denotes complication of fetal development during fertilization (all genetic material from the mother is lost). Instead of an embryo, we get a birthmark (a group of cells that will develop into a cyst) but which still produces hCG hormones.
