4 days late.. is it ok to scuba dive??

I'm wondering if anyone out there in glow world can help with this.. I know there's little info and research out there about diving and pregnancy, and the main recommendation isn't to mix the two.. but I wondered if anyone knows any detail about whether it's ok in the very very early stages?? I'm 4 days late for af, but I'm not getting a positive test yet.. I have a 3 day dive trip starting tomorrow that'd I'd really love to do.. but feel uneasy about it due to potential harm to something that might not even be real. Any advice?
