4 days overdue... :-/

...and.nothing feels different (as in, signs of body gearing up for labor). Are there any weird things ppl's bodies did before they went into trye labor? (NOT water breaking or mucus plug...I know those!). Like, for example, today I've had more gas than normal even though nothing in my diet has really changed. Is that anything or just wishful thinking? Anything else that could be my body cluing me in that this is coming...?
