Nervous because i have 5 days until my next period is suppose to start

I am super nervous because my husband really wants a baby. We have been trying for months and nothing has happened. My youngest daughter keeps saying mommy's pregnany . I want so bad to believe her because they say kids know. I'm just so unsure what to think so I'm kind of on edge. The more days that pass the more nervous I am. Im praying that what my daughter says is real. I do want yo believe her but part of me thinks she says this because she wants another sibling. Comment below your thoughts plz...
