This may come as a surprise to you that the answer of no diving during pregnancy isn’t based upon sound medical research, but it’s the right answer. Your developing fetus isn’t protected from nitrogen bubbles. This means there’s a chance of a theoretical risk for injury Whilst the evidence for this is not fully scientifically proven, the information that is available suggests there are potential risks. The risks from a pregnant mother scuba diving to the unborn baby aren’t worth taking. These risks include possible complications caused by decompression on the ascent from a dive.
