The 1st day of my LMP was April 1st 2011, so that made me due again April 29th. My periods are very regular. I am breasfeeding a 22 month old, but periods have still been regular since he was 1 year old. This is May 10th and still no period. I've taken 6 home test and all have come out negative. Should the test be accurate or is it highly possible the test are being done too early. Also, I have IBS and that has completely stopped, I am more tired than usual, and it hurts when my son breastfeeds as if I just started nursing.
