Hey,
I always get more blood streaks and sometimes outright bleeds around my period. Generally after about a month post-hospital I start getting streaks in my mucus though and obviously my health status isn't very good since I'm waiting for a transplant!
I never change my care routine unless I have a major bleed, then I give it 24 hours to settle down before I do any more pulmozyme or anything, but with streaking I don't worry as in myself I haven't noticed that streaking leads to big bleeds at all.
Don't worry,
Frito
