I'm 3 days late ... but more worried that this is another sign I'm getting old and the change may be about to hit me 
I'm 30, have 2 children, and most recently, 2 MCs (last one May 2012). Since the MCs, my cycles (days apart) have not been the same each month, ranging from 28 days to 31 at the most, but still fairly light period's lasting for about 4 days really. I'm not on the Pill, or any other contraception.
Had 2 bouts of UP sex during my fertile / ovulation days and have since had very sensitive nipples. Done 3 preg tests (the last one early on in week, before my P was due) but all negative 
Not actively trying to get pregnant, but do you think I may've just tested too early and this is why they were negative? Or could the 3-days late be something more sinister? My nan, and mum both went through early menopause and I'm wondering wether this is hereditary?
