I am 36 I had a c-section and a tubal ligation aug 17 2011, went till November 2011 before I had a period.. my periods were heavy and sometimes I would go 9 to 10 days then in July I started the 5 went around 7 days not as bad and this month I haven't had mine yet and its aug 25 which mine hasn't been normal should I be worried about this?. in November of last year when I had the heavy bleeding for a few months I gained weight all at once but I have lost that..
