late period

We have been ttc since November, so around 8 months and still nothing. My period was supposed to start today but hasn't yet. I know it's common for periods to be sporadic, but mine is typically pretty regular. Hoping, praying, and crossing my fingers and toes that it does not start!! Happy vibes, thoughts, and prayers would be greatly appreciated. We just bought a house so adding a new baby to the mix would just be icing on the cake!!😁😁😁😁 If I get another negative I don't know what I'm going to do. I know it takes time, but I'm just running out of patience and hope.
