All the symptoms you reported (continuous bleeding everyday heavier than spotting, slight abdominal pain, weight gain and moodiness) might be side effects from taking the birth control pill. The problem with the birth control products that contain hormones is that no one can tell how exactly the body would react. Sometimes prolonged bleeding might happen like in your case. Sudden unexpected heavy bleeding might occur, too. Women miss their periods on occasion when they are supposed to have them. There are many variations that are influenced both by the specific birth control product and
the responses from the body which are different in every woman.


You might want to visit a gynecologist and consult which birth control product available in your country (not provided) might be best for you. A physical examination might be needed to detect or exclude any pathological conditions.
