Late?

Amber • Have one sweet lil lady, but she would make one awesome big sister:) Trying for baby #2 for 5 years now.
My period is a day late, well sort of. I'm usually 28 days, but the past 3 months I have been havin 24 day cycles, I'm on day 29... Could I be prego? Should I risk a test? Or wait for a few days? I've been trying for over a year now. So I'm really hoping:)
