Heavy Period SOS

So hubby and I are just starting our TTC journey. I have PCOS and my doctor put me on Provera to regulate my ovulation. I have had the worst period of my life - such heavy bleeding that going to the bathroom every two hours doesn't keep me from bleeding through my clothing. 😕 Tampons are a no-go for me (they've always been too uncomfortable down there), so I've just been struggling through my days. Anyone have any useful tips?? Spoke to others with PCOS who said an unusually heavy period is common when you first start Provera, but holy moly, I'm praying hard for an end...
