Not sure if I am or not

Jessi

So I’m 7 days late on my period, but last month I was 7 days late and got my period.. and I had a dream I was pregnant so I’ve done a test this morning and this has come up very faintly... still don’t no wether to beileve it or not because I’ve done two test prior about a week ago and they came back negative... what are your opinions?
