i was told by a doctor that if you bleed it could last from anywhere 6 months to 1 year or as little as just a couple of days, I experienced continuous bleeding for over a month now, I went to the doctor and they suggested that I start the pill to regulate my periods and get this ladies they gave me Ibuprofen to stop the bleeding, I had 200mg but they prescribed to take 600-800mg at a time 4-6 hours for 4 days and guess what?! I stopped bleeding that day!:) I sure hope this is helpful to someone because I know how stressful it can be to have a period for a month straight and who knows how long it would of been if i wouldn't have found out about the Ibu.!:)
