Clincial guard opks?

So since yesterday I have had sharp side pain in my left side and very nauseous I think I'm ovulating I always get the side pain when I ovualte plus this am woke up to a pink tinge in my cm. But I finally for my clinical guard opks took one around 230 and one are 615 and both were neg! Usual I use wondfo and have no problems but this month I went cheaper! Has anyone got negatives on these opk but ovulated? I'm baby dancing just incase! Also I read that nauseous during ovulation is normal and can be bc of a rise in hormones could that be true? Help!!
