Running a fever

A

I'm about 4 weeks and I woke up in the middle of the night (3:30) running a fever. I have different thermometers and each gave a different reading one said 101, the other said 100.6. I took a little Tylenol and put a cool wash rag of my forehead and my fever did break.

I woke up this morning without a fever and still no fever yet (7:30) so it could just be the meds keeping it away for now. Should I be worried for the baby? I did some research and found mixed answers about fevers affecting babies in the womb and I haven't started prenatals because I just found out a few days ago I was pregnant. I plan on calling the Dr as soon as they open.
