I am 36 and very regular like clock work. my husband and I started ttc in the last month. my period was three days late but then I went to the bathroom and there was blood. it wasn't heavy and a actually went away after a few hours. the next day it was back and heavier then the previous day. the third day there was still some cramping but just light brown when I wiped. I am not sure if it was my period or what. I was having a lot of the early pregnancy symptoms as well. could I be pregnant or just a coincidence that the month I am ttc my period is three days late.
