Help me Out

Okay Ladies.....I am 33 weeks 5 days. I have had horrible indigestion and constipation this whole pregnancy. I have been super tired as well. BUT....Today I woke up feeling GREAT, I have energy, no indigestion, I actually have diarrhea (which at this point Im thankful for)! I dont feel so huge....I actually simply dont feel pregnant. Other then the baby moving...which doesnt hurt as much today as previously.

Has anyone else experienced this? Does this mean labor is coming? How soon?

Help me out!
