Hi, I am a nearly 47 year old female, and came off the contraceptive pill last October. Since then my periods have been really erratic - sometimes 13 days between, some 22 days, and then this month 30 days. I had my period for 4 days, but then three days later every time I go to the toilet a little bit of blood is there - is this normal? I have been like this for 5 days now
