So ... a few years ago somebody I know who also suffers with flooding recommended I try a menstrual cup after seeing me rush to the loo every 5-10 minutes for an hour or more at a time.
I was a bit nervous and didn't immediately do anything about it, I figured that if I didn't get along with it, I wasn't at home during the bad times and it could be a disaster.
Just this last week, I bought a 42ml cup (supposed to be for those who have had kids but I figured I should get the biggest capacity as I believe tampons hold about 18ml and they can last me as little as 5 minutes). I have to say I am very pleasantly surprised. At my worst, I need to empty etc every 30-40 minutes but this is a huge improvement for me! I can go out feeling secure when I am bad, which I have never been able to do before, I would usually just stay in.
I just wanted to share my experience as this has really made a huge difference for me! Anyone who suffers with flooding to the point it keeps you from leaving the house, please consider a menstrual cup. They take a little getting used to but a) you'll save a fortune on tampons/towels and b) it could give you security for a much longer period than conventional sanitary wear.
Wish I'd got one years ago when my friend recommended it!!
