### output:

Hello and welcome to Chat Doctor. Thank you for your query. There are two-three possibilities from your description, and I shall explain them to you.1. Birth control: The initiation of birth control can easily cause side effects like lower abdominal cramps, mood swings, slight discharge (blood), etc. Thus, what you could be experiencing could be side effects of the birth control. You could consult your prescribing doctor and report the same2. Pregnancy: This is always done. Is routine in patients experiencing such symptoms, this I request you to conduct a home pregnancy test, which is to be done at least 20 days after your last sexual contact or on the first or second day of a missed period. An early morning urine sample should be used for most accurate results. This test might have to be repeated 2-3 times for an informed result3. Infections: As you are sexually active, the possibility of an infection, will have to be ruled out as welly opinion would be to consult your doctor, and find the cause for your presentation, which should most probably be one of the above conditions. I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you. Best wishes.
