I had got one positive on 5/11/16 , the day I was suppose to get my period . That was a clear blue regular test (not digital) . Then on 5/13/16 I took another clear blue and got negative . Then 5/14/16 I took a first response regular one , and got negative as well. Now I'm 45 days into my cycle. My last period was 4/8/16 and I have yet to get it . It's 5/22/16 now . I had a blood test that came out negative as well. Is it possible that I'm pregnant ?
