Faint positive line !!

Katherine
Okie everyone so I have PCOS and take no meds what so ever and use no protection . I've been feeling bloated random cramps and sometimes nausea. But the nausea started this week only twice. Last night I took a HPT and said negative :(( I wanted 5 mins and clear as day it was negative ! Keep in mind I'm using the new EPT plus and minus test . This morning I woke up and checked it idk why I did but I did . So there was a very faint horizontal line !!!! So it made a plus sign !! I was so excited and I've been reading and it says it's almost impossible to get a fake positive . So I was super anxious and nervous so I went out and got another one but it was negative . Could it have something to do with the fact that it was left over night that gave it the faint line ? Was it maybe a bad test ?? Anyone have this before by any chance ?? Should I be testing in the morning instead ?? This would be my first pregnancy so I'm hoping I am !
