I found out when I was just about 5 weeks along. I was shocked b/c I had suspected I was pregnant and took a pregnancy test that was negative. Barely a week later, I bought another home pregnancy test and this one resulted in a positive...VERY light pink line, but it's definitely there! I wish I could offer more advice, but this is my first. I have no clue what I'm doing. I was really surprised to find out that I was pregnant b/c I had what felt like my usual period cramps and backaches. I read your earlier post - - I would go get a doctor to do a pregnancy test. :)
