Ok, if you've read my threads before, you know I am ttc and have been for 5 months or so. well my cycles are mostly 28 days and my periods 7 or 8 days. Well my period came 2 days early this cycle and only lasted 4 days and then 1 day of spotting (brown) and then today I had brownish stuff, (sorry if tmi) but not like i've seen before. Could this be implantation bleeding???
