How do you know if the spotting is from pregnancy or the morning after pill?

Spotting can occur for various reasons, including early pregnancy or side effects from the morning-after pill. If the spotting is light and occurs a few days before your expected period, it might be implantation bleeding related to pregnancy. In contrast, spotting after taking the morning-after pill is often due to hormonal changes and can occur at any time in the menstrual cycle. If you're unsure, it's best to take a pregnancy test and consult a healthcare professional for clarification.
