While using tampons on my period they have been filling up with a clear, odorless liquid. I have been getting very minimal blood but i seem to keep getting this fluid for the first 2-3 days of my period. I have also used pads and even they get filled with this liquid. There is so much fluid that i have to change pads or tampon every 1-3 hours and most of the time it soaks through my underwear as if i peed but i did not. It only happens during my period and thats it. It has been happening for some time now and my period seem to be more irregular than normal. I have no kids although i have had to have a D&C before due to a miscarriage and i am not currently on birthcontrol although i ve been on depo and arm implant in the past. No doctor has seem to know what the cause is. Sorry for the TMI.
