Advice. Hottub pregnancy scare!

My husband is a owner of a gym. I go up 2x a week for sauna & hot tub. As of yesterday I believe I’m about 6weeks pregnant, I’m going to confirm at docs soon. But the scare is I just read hot tubs & saunas for over 10 mins over 102 degrees, can cause brain & spinal developmental issues in early pregnancy phases. Has anyone any concerns, advice and maybe this is a help to anyone attempting to get pregnant. No caffeine & no really hot gym situations. I’m worried because we want a baby, but I’m terrified we messed this could have harmed our process.
