I'm 52 years old and my periods are not very irregular.  Last heavy period was 7 mos. ago.  Had a very light period 3 mos. ago, otherwise no periods.  Three weeks ago I got a very light period and has been steadly getting heavier and heavier and the last 5 days has been extremely heavy.  I go thru a super+ tampon every 3 hours and a pad 4 times aday.  Its bright red.  Is this normal?  It's shows no signs of letting up.
