Ugh. Help):

My cycles and symptoms of AF have completely changed since my miscarriage... I used to be 32 day cycles. Now the past 2 were 28, 13, and she should be here within the next week. But who knows?!? My symptoms have become more like pregnancy; sore breasts and nipples, small twinge like cramps, and my cervix won't make up her gosh dang mind. Before I only cramped as I bled, and my breasts were only a bit sore never my nipples, and cervix was "normal." Is this normal? Does having a miscarriage screw your entire cycles up for awhile?
