Has anyone overheated in pregnancy?

We’re on vacation, 4th day here and we went out on the boat for just 2 hours. I drank 3 water bottles in those two hours, wore 50spf sunscreen (I have not burned) wore a hat, and after I felt myself getting a bit hot in my bathing suit, put on a white long sleeve fishing shirt and kept hosing myself off to keep it wet and cool.

On the way back I started feeling like I was going to faint despite my body not feeling hot and getting the air in my face from the boat ride. Husband hosed me off more and I splashed cold water on my face.

I came back to the house, sipped some coke (i thought maybe sugar?) drank a cold water and ate a sandwich sitting in front of a fan. It took me 30/40 min to not feel dizzy anymore and for my headache to leave

I’m almost 8 weeks pregnant.

I’m so worried I harmed my baby. I tried taking all the precautions and being prepared and still ended up feeling bad.
