Sauna safety during pregnancy

Omg ladies. I'm TTC and I accidentally went into the sauna yesterday without thinking. I was in there for about 15-20 mins. I was drinking cold water the whole time. Will that affect me getting pregnant or anything like that. I was not overheated and felt fine after. I read that it's dangerous to the baby if your body temp rises to 102 degrees. But I have no idea what mine was. And I don't even know if I'm pregnant yet. I've been feeling pressure down there. I'm so anxious , please help.
