my friend told me this is noraml after 40's 

Knowing that from more than 2 years the perod was heavy for nearly 3 months (I was using
Helix contraception, the same one for 10 years and the doctor erased it )  and The doctor gave me Sterionate Nour and after that It becomes very good and little 
from this time I did not use any means to prevent pregnancy ...

Thank you
