Can You Get Paternity Testing While Pregnant?

Pregnancy is one of the most vulnerable times for a woman. A study in 2015 found out that people who are completely economically dependent on their spouses are more likely to be unfaithful.

Men are less likely to cheat if they make more money than their spouses. Studies from the Journal of Social and Personal Relationships estimate that the average person of the opposite sex has a 42% chance to cheat on their partner.

Here is everything you might need to know about paternity testing, even while pregnant:

Can You Do Paternity Testing While Pregnant?

A paternity test usually involves DNA samples to be taken from the pregnant mother and the titled biological father of the child. This is usually in the form of blood samples. paternity testing is usually more than 99% accurate.

Studies show that women who are at least 10 weeks pregnant are allowed to get a paternity test.

There are various paternity tests that are available to choose from, but some are more dangerous than others. Usually, non-invasive prenatal paternal tests (NIPP) are safer and less likely to harm the child.

In some states, it is illegal to perform invasive paternity tests as it can directly harm both the mother and the child in the

Here are some types of tests that you should know:


As mentioned earlier, the non-invasive prenatal paternity test is a type of paternity testing that does not involve touching or hurting the child. This type of paternity testing while pregnant usually involves taking blood samples from both the candidate father and the mother of the to-be-born child.

NIPP then compares the blood samples to construct a unique fetal cell. If this fetal cell resembles anything like the fetal cells present in the mother’s bloodstream, the alleged father is 99% accurate to be the father. Non-invasive prenatal paternity can be performed 8 weeks after being confirmed pregnant.


This is a type of paternity testing that involves invasion. It might be illegal in some states and require signing forms in many others. Amniocentesis can have side effects like:

  • Cramping
  • Leaking of amniotic fluid
  • Irritation
  • Vaginal bleeding
  • Risk of miscarriage due to premature labor or infection

Amniocentesis test involves using a long thin needle that takes a sample of amniotic fluid from the uterus. Amniocentesis tests are usually accurate when done between weeks 14 and 20 of pregnancy.

Chorionic villus sampling

Another type of paternity testing while pregnant, chorionic villus sampling is an invasive paternity testing method. This test also uses a thin needle or tube that is directly inserted into the vagina through the cervix to extract chorionic villi.

This tissue can then be compared to the DNA of the alleged father to find out whether they are the father. Although this test is accurate for 99 patients out of 100, 1% of all tests result in miscarriage.

We understand why you would want to perform paternity testing, but personally we would recommend doing one after the child has been born or go for non-invasive paternity testing. The child did nothing wrong, and it does not deserve to be put through the risk of miscarriage.
