I was supposed to have my period on the 05/13/12 its now the 05/17/12 and I took a pregnancy test yesterday the 05/16/12 and it said I was pregnant and to make sure I took one again today morning the 05/17/12 and it said that I'm pregnant again could it be right? Isint it too soon to be testing if I'm pregnant? I'm confused.

No its never to early. You are most likely pregnant but to be 100% sure go to your doctor or clinic and they will let you know for sure
