Park Embarrasment

Ok, so I think I've told all of you about the whole "me pretending to be pregnant at the park in order to not make some random girl (aka "cool mom") feel embarrassed", so now I need to know...do I never set foot back in that park (this option sucks cuz it's a really cool park) or what do I say if I run into "cool mom" again? Do I tell her I had a miscarriage (such super BAD karma) or do I be honest and hope she finds the "story" quirky/charming and befriends me anyway. Please help...
