The user's question is about why their period is very light after giving birth and starting continuous birth control pills. The user mentions that they used to have heavier periods before pregnancy, and now they only experience light spotting. They also mention that they did not breastfeed and were not on the same birth control pill before pregnancy. The user is seeking clarification on why their period is different now compared to before. The possible explanation for the user's lighter period after giving birth and starting continuous birth control pills is that hormonal contraceptives can often lead to lighter periods. This change in menstrual flow is considered normal and safe. However, it is always important to rule out pregnancy if the period is significantly different from usual. It is recommended to take a pregnancy test to exclude this possibility.
