Hi Starla and Dee,
As Sparkle has said I think this sort of change in menstrual loss is very common, in fact it seems that almost anything can happen. Some ladies get heavier, some lighter, some chop and change between the two. The possibilities are endless. The good thing about this site is that you can always find half a dozen other ladies with similar experiences to you.
Knowing that all is normal makes us feel easier, less isolated. When you feel low pop on here, have a chat, there's normally always someone around. x
