Light brown discharge?!?

Kealohi • Hi! Im kealohi ☺️Im 21 years young and am ttc baby #1 with the love of my life 💕
Okay ladies sorry if this is totally TMI.. I am 5 weeks and 2 days pregnant. Today towards the end of the day I noticed really light brown spotting in my underwear. No cramps or anything just nauseous. I wiped and there was practically nothing. Any ideas???
