Could I be pregnant? Help please

Just wanted to ask, I’m either getting vvvfl, or I have line eyes... but I’m 2 days away from AF but i have mild cramps and lower back pain. Also tension headaches these last few days... my nose is also really dry that when I pick it, I get a little bit of blood... all signs I had of pregnancy with my first pregnancy. If I am pregnancy why do I keep getting BFN? Could I truly be pregnant again? Usually when I get my period I don’t have cramps before I start it. The little line I do see hasn’t gotten any darker in the last 4 days since I retested... and always FMU

r any other symptoms.. my periods are good at surprising me. Anyone else have had similar experience and ended up pregnant?
