i've asked doctor about this problem,
cos i got M last Mon (~52day), fresh red in colour, amount just little, no need to use M pad, but only "liner", last for about 3 days...at the same time, my face got acnes, the amount that i have never had before(over 30+) :-(
the doctor said breast feeding can also have M...it's about the hormone....no need to be afraid...can have breast feeding...
