Can Anyone Help me out there??? Ok this is gonna be kinda long and I am sorry for that LOL! 
I had my last period on Feb 12, for the past three months they have been coming on the 12th every month! On March 11th I started spotting brown blood...which I figured was AF coming so I was ok with it....Well it has now been 13 days and expect for one day I have been spotting brown and pink blood and once it was a red color. I have all the symptons of pregnancy from nausea, to peeing, headaches, breast soreness...all the normal pregnancy signs (I have two children right now)...But I have taken 2 HPT and they both came up neg! Can anyone help me?? What the heck is going on with my body if Im not pregnant...why am I still spotting almost 2 weeks later and its brown not  red. I usually spot in the very begining of my cycle..the first day...then it goes to full blown AF!! I am soooooooooo confused!!!! HELPPPPPPP PLEASEEEEEE!!!!!!!!
