Is there a chance I hurt my baby?

I found out I was around 4 weeks 3 days on Friday. I live in a cold area and I sleep with my heater next to my bed, I normally turn it to half way but I forgot. Friday night I woke up in the middle of the night sweating everywhere and the room like a sauna. This happened twice now. I’m really concerned I might’ve messed up the development or something as I heard if you get overheated it can harm the baby. I have no idea what my temp was. Please help :(
