I had been a faithful user of both the diva cup and the keeper for years, but they are now too small for me after childbirth. I am 5'10" and 210 lbs or so. I am not happy to be using tampons again. It looks like the diiva cup is one of the largest according to the size chart and it is too small. Is there anything else that might work? I am 34 and my flow is beyond heavy especially since I am breastfeeding. Oh, and also I live in Canada so I am not sure if everything is available here.
