i am on birth control pills , i was suppose to start my period on the 17th of this month, i did not start which was odd because i been having a period every month at the same time. i was was very light spotting on the 19th and 20th only lasted 2 days then i stopped it was really weird cuz i wouldnt even bleed on my pad it was just when i wipped and it was hardly anything. i still been continuing to take my birth control pills todays was suppose to be my last day on my period but like i said it only lasted 2 days i been having cramps and back pain and diarrhea i was just thinking maybe i caught a flu or something. but i dont know . what do ya think ?
