Okay I my husband and I had unprotected sex I believe the 2nd week of June I'm not suppose to start my period until June 28th well I started bleeding on June 16th but it brown at first then the next day it stopped and the next morning I was bleeding it wasn't heavy but it wasn't spotting either I've took test and they come back negative?

Way to early to take a pregnancy test. You will have to wait till the weed of the 28th or when your period is to start. Wait that entire week to see if it is just late. Then take the Home Pregnancy test.
