Another potential that we don't like to bring up is that if you have PCOS, your chances of having an early miscarriage are increased. As a result, it is possible to test positive for pregnancy and then have a negative result on a subsequent test. When you have PCOS, your hormone levels are erratic, thus false negatives are unavoidable. False positives are also possible if your hormone level is not high enough to show up on the test. A woman with PCOS who wants to know how likely it is that she will get pregnant may be advised by her doctor to take a home pregnancy test after each menstrual period until she gets two consecutive positive results. This approach can give us an idea of how many eggs are being produced by her body. However, since women with PCOS tend to have higher-than-normal numbers of ovarian follicles, this method could cause you to think you're pregnant when you aren't if too many tests turn up negative. It's best to ask your doctor how often you should be taking pregnancy tests, as well as what number of negative tests should pass before you assume that you are not pregnant. Women with PCOS are at increased risk for ovarian cancer.
