No period but pregnancy test is negative...advice please

I was suppose to start my period 5/27 and I have still not started it. Took a pregnancy test it was negative... could it be to early to tell?? Also I had a baby 4 months ago and I never breast feed so my milk dried up after about a month and a half..and three days ago I start leaking milk?? (Please I know I just had a baby it's our choice to have our kids close in age so please no mean comments) thanks!
