I've been on Cerelle for years(!) I think over seven. I've never had a period since starting the tablets but today have had quite a large bleed. Sorry for tmi, but it was enough to ruin my underwear and come through my dress. I've been wearing a pad since and there's been nothing else - even when I wipe after using the loo. I've had a really heavy feeling down below for a few days and it feels worse now. Is this something I should be worried about? I'm 49 btw. Thanks
