So my period was supposed to start on 5/27, its now 6/2, no sign of my period yet. My breasts have been tender for almost 2 weeks, I'm emotional, eating like a cow and I've taken 4 pregnancy tests. The first one popped up with a faint positive before bed so I took one the next morning with my morning pee, it came up negative. I took one again night before last and it was a faint positive as well, so I took one the next morning with my morning pee and it came up negative.I'm not sure what to think at this point. Any suggestions to what could be going on?
