Jumping while pregnant is bad news. Yeah, we all know skydiving is relatively safe (at least compared to the public's perception that half of us are suicidal), but it's still a high-risk sport! The hard openings, bad/off landings, and other things that we hardly think twice about might not hurt you, but they can kill or otherwise severely harm a fetus. Pregnancy is 9 months of sacrificing your own pleasure to get that baby into the world...my medical opinion for pregnant women: don't consume alcohol, try to eliminate tobacco and other drugs, and no jumping out of airplanes!
