I’m late

I’m 18, as of today ( the 27th ) I am 8 days late, I took a first response pregnancy test on the 25th and it was a night pee and it was a very light 2nd line in which was confirmed in the faint lines topic ! I took a digital first responseone in the morning the following day & it was negative & I took one this morning ( the 27th ) a digital clear blue and it was negative. I’m having some cramping and feel extremely bloated like I’m on my period and I don’t know if im delusional or my hCG levels are high enough to be able to test this early ? I’m so confused , is there a chance maybe I got a light fake positive test ? When do I test again ?
