Line eyes???

So i came off the contraceptive pill and we got pregnant straight away... a few faint positives and a digital with the words pregnant then i came on heavily (13th of may) .. went straight back down to not pregnant a day after bleeding started. Its now been 2 weeks and i shouldnt have even ovulated yet but i had a cheap test left and just wanted to check it was still neg (clinging on to some hope) and have a ver very faint line were it should be pos :( so confused! Is it even possible to be pregnant this soon after?
