opk's line or not

[sassy123]

hello,
i have been having around 30days cycles for the last few months. cd14 i got wat i thought was a positive is was very dark but stil that fraction lighter then the other line then yesterday cd15 i got a another line that was like half the darkness. when i went to compare the lines the one from cd14 it went light.
so i guess my question is do i still get a line after i get a positive? if i am right i should of o'd on sat. being that i get a very dark line (but went faint the next day) and i have had ewcm sat and sun (cd14 and cd15).
so do u think i o'd. i was had the idea of takin a pic o the tests but liek i said they haev faded.
