Natural remedies

Well AF has reared again this month, if it's isn't bad enough I've not managed to TTC again...my period is like a week spent in hell. I have to change approx every 45 mins, last month I ended up with dehydration because of the amount I lose. Then there is other problems with yeast infections because I change tamps that often (pads are just a no go because I lose that much). Does anyone know of any natural medicine that can help me deal with the discomfort? I know if I go to the doctor they will give me something but I want to try and be as natural as possible! Any advice would be great!xx
