OPK Confusion

Alexis

The top test is this AM. The second is PM (5:30ish). I usually get positive OPK at night, but I didn't even think the top was positive. Is it? Should I test again in the AM? Is that a normal drop? The only symptoms I've had today were sharp cramps and we did just start using preseed this cycle. Glow predicted O day tomorrow, but it is usually a day off. TIA and Baby Dust to all!
