4 days late"

So I'm 4 days late and I had done many pregnancy test some came out with a faint line after a couple of minutes , the rest negative especially the first response negative. But the weard thing is that I been having cramps the whole month since 1 DPO, I also had sore nipple for like 2 weeks now I'm ok... So my question is those anybody had this symptoms and at the end they got a positive ?? I'm super confuse right now...🙄
