I need OPK help! Please!

Emily • Sat, Jan 06

First time ever using opk. Took an opk last Thurs. 28th, it was positive. Still positive on Friday/Fri evening. We BD'd 25, 27, 30, and 31. I haven't been feeling right and just randomly threw up because my mother-in-law was cooking and the smells didn't settle well with me.

My question is, is it too early to be feeling nauseous and vomiting from pregnancy? idk when I actually ovulated because I don't understand the tests that well yet lol
