My periods keep coming later and later than my due dates and for the longest time it was heavy with lots of clots for the first 2 days and then almost nothing. Last month it was almost nothing the whole time and this month it is so heavy that I have to keep changing frequently.

I need your advise on what's happening. I am 46 in May and I have 3 children; 12, 13 and 16.

These are my calendar dates for my periods:-
2012:
June -24th July -22nd Aug -unrecorded Sep -11th Oct -9th Nov -14th Dec -19th
2013:
Jan/Feb -unrecorded Mar -14th Apr -26th

Have you seen your Gyn lately for your annual exam?
