Unrelated: Bactrim (sulfamethoxazole and trimethoprim) does not affect menstrual cycles. The changes in your cycle could be coincidental . It could also be related to whatever infection you have that caused the doctor to give you antibiotics. Regardless you should not take the medication in a way other than what was prescribed by your doctor.
