Tanning

I want to lay out in the sun today because I am so pasty white that I'm basically glowing lol. I'm going to keep hydrated and use sunscreen of course, but what I'm worried about is my stomach getting too hot.. idk if this is stupid to think but if it gets too hot will my baby get too hot and boil up!? And will all the fluid dry up? I'm just trying to be extra cautious 🙈 I'm 12 weeks and 5 days
