We had tried for so long to get pregnant, that when I thought I might be I did NOT want to test b/c I didn't want it to be negative.
So I waited a long time to test, thinking that surely AF would show up.
Then I got this:http://badkitty.dreamingheart.net/test2.jpg
Now, in the picture it definitely is a positive, BUT I promise you that IRL, that line was BARELY visible. I was completely confused. Is that a positive, or isn't it? Did I wait too long to look at it? I had read somewhere that ovarian cysts can cause a false positive, and I have PCOS, so I was terrified that it was just cysts popping up again.
I tested again and got the same exact results.
Finally someone said to me, a line is a line is a line. So I scheduled a test at a doctor's office. It was positive, and I was already at 10 weeks!
And now here I am just about to pop!
The truth is, those tests aren't perfect and they don't work the same for everyone. I was already 10 weeks and figured the line should be pretty obvious. I know another girl who kept testing all throughout her pregnancy and never got anything but a faint line.
The best thing you can do is get a blood test.
