A new study published in Obstetrics & Gynecology found that more than 40% of women test for pregnancy several days before their expected period, increasing the likelihood of confusing results, such as false negatives or early positives followed by negatives, that may reflect very early pregnancy loss. Alexandra Sundermann, MD, PhD, said the findings highlight the need for clearer, evidence-based guidance, as testing too early can lead to unnecessary emotional distress and misunderstanding of results.
