Could it be soon?

Since Friday I have been experiencing a low back-ache off and on and some noticeable contractions. I have noticed that my belly tightens up considerably every time my back-ache gets worse but I wouldn't say that the belly tightening hurts - sometimes I don't even notice it unless I put my hands on my belly and can feel the tightening that way. There are also some other signs I have been experiencing since Friday but I won't bore you with those gory details except that they do point to labor happening soon. Also, this morning I woke up and noticed after getting dressed that she has dropped considerably. I actually look less pregnant now! If you all could keep us in your prayers (as many of you have already told me you are doing) - we would really appreciate it. Hopefully this means we will be having a baby soon!
