IM SO CONFUSED!! ( FIRST TIMER )

Princess

I need your help ladies! This is my first cycle doing OPKs. This morning My test line was light, but i was feeling a little nauseated - so i thought why not test again just to be sure.. Well, when i did it popped up dark like the control line.. I dont want to miss my ovulation, can anyone tell me whats going on? TOP: First morning urine - BOTTOM: Afternoon urine
