possible overheating 13w

hi, i am 13w4d. i went out on a bass boat today (cleared by OB) to do some fishing. i live in the south and today’s high was about 95F. i was doing good and standing up fishing and the boat started rocking a bit and all of a sudden i got a bit nauseous and light headed. i immediately sat and sipped some water. we were out on the water for around two more hours. i sat under an umbrella with a handheld fan and drank water the rest of the time. i was already nervous about going out and now im absolutely panicked that my core temp could’ve raised high enough to serious hurt my baby. i started feeling better within 5 minutes of sitting. i was sweating on my legs that were still out in the sun but otherwise my color and all was normal and i started feeling better just hot. i’ve been home for hours now and just have that sticky feeling after being out in the sun and tired. should i be concerned about this? TIA
