I have been on my period for over a month and it has been really heavy. This week has been worse, it went from a medium pad every 4-6hours to a heavy pad every hour or two and when i go to the bathroom there is a stream of blood but without any abnormal sensations (no burning or pain aside from cramps). I have an IUD, non hormonal copper. I have had one kid(4/5/15) via c-section, also i have HPV. I think that everything relevant.
