Opk question ?

Rachel • 12y.o girl💕1y.o🌈boy💙 🤰🏻w. #3✨ 4 👼🏻

This is our first month TTC. We started yesterday with OPKs. According to glow, I’m supposed to ovulate on 1/1. Yesterday and today, I’ve gotten nothing on opk. Not even the faintest of lines. Should I be worried or is it still too early for lh surge to show? I don’t know anything abt it lol.. please help!
