i would go for it, my husbands best friend plays in a bang and he had a gig 2 days before my due date and everything went fine, just make sure you have a plan for which ever way things go - if you have bubs ealier is there a sitter, will you still go etc ... if you go into labour there, make sure there is someone to take you to the hospital etc .... if you're still pregnant and dont go into labour enjoy sometime out before you have another bundle to look after
