is this finally my positive? please someone?

sooo i got a nearly positive opk on cd 12/13 but the opks i have arent great they take 30 mins to finish there result as it says and they dont have alot of dye so i thought that was my + as i did get a temp spike but this morning my temp dropped so i did a opk and it was so dark compared to the rest i had i will post them up

first one is leading up to cd 12, and then todays

 

looks like im the only one people arent replying to!

 

heya thanks well it was my + because the next day it was negative and my temp spiked so i ovulated that day! lol luckily we bd the day before this anyway and then when i saw it was + i made sure we dtd again that day so i feel happy about that

 

although im totally confused because i started getting some symptoms yesterday and i was like no its way too soon so thought nothing of it, then this morning i put my details into another charting site and it reckons my ovulation day was on cd 12 because of my short cycles :/ no idea now how many dpo i am cuz i did get another opk like that on cd 12 so ill have to see lol
