<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am currently starting my third month of birth control quasense. The first month I had no issues, no spotting. But within the second month I ve experienced spotting. I ve had unprotected sex at least once. I am now experiencing heavy thick brown blood on some days and others its light and thin. I ve had an increase in my trips to the bathroom. Is it my body adjusting to the medicine, or could I be pregnant?  <response>: Hello dear. Understand your concern.no need to worry dear, its just side effect of BCP birth control pills.in earlier months, some have some side effects like spotting, irregular heavy bleeding, pain cramps, headache,nausea, tenderness in breasts, weight changes...so no need to worry, just be calm. Look, every contraceptive methods has some failure rate, BCP has 0.5-1 failure rate. You have that symptoms, that does not mean you are pregnant, so be relaxed. Hope this will help you. Best regards. Chat Doctor.
