In december I had normal 28 day cycles, we decided january would be our first month. my jan cycle was something like 30 days, my feb 31. etc etc, now in may i missed my period which at the time was 37 days long, i found out i was pregnant but miscarried at 7 weeks, for this month (3 months after miscarriage) i calcualted a 37 day cycle, i was a week late putting me at 44 days, so i havent got a clue this month lol, but good luck and lots of baby dust x x x x x
