So DH and I are going on vacation in 2 weeks and I'm really early into my pregnancy... Like 4 weeks, 1 day early. I haven't had my first appointment yet and probably won't until we come back from vacation. I had plan to snorkel a lot on this trip (using just fins and a snorkel mask) but now that I think about it, I wonder if there are any precautions with being underwater. Any bees have any experience with this? Any advice would be lovely
