Nesting !

When did your nesting start? The first, second or third trimester? Also did you have nesting constantly? Like every day til baby came since it started, or did it occur spurratically (sp?), as in you had it a few days in each trimester, or every once in awhile?

I remember my first pregnancy I had it on and off through out, but once my water broke I went into super cleaning mode and made sure everything was ready when we got home!!

This pregnancy I haven't had it much. It's been one day here and there. I'm wondering how you other ladies nesting experience go. Sometime I feel so bad for having no energy to clean
