No AF yet?

Lesley

Okay so I am due on my AF today, and 2 days ago I took a home pregnancy test. This came back negative...

I'm not sure whether to take another one? As Iv already had a negative. Please help.

Does the HCG vary in different woman?

And I would like to know when you ladies had a positive, how long did it take you after your missed AF to get a positive?
