I just found out I was pregnant yesterday with our second and I am super worried that I put baby at risk for NTD. I live in the Midwest and we had a heat index warning (100 degrees) and I was out in my garden for a half hour or so ( I was in head to toe sweatpants because the bigs love to bite me). I came inside and I was drenched with sweat and stripped down to take a cold shower. I then took a test and it was positive. I am so incredibly concerned that I have unintentionally harmed baby.

You are likely fine. Ask your doctor when you make your appointment, but your body is a good insulator for your baby.
