TTC.........

I am 12 DPO and am late 5 days, took a pregnancy test the day before my missed period and the day after and both negatives, is it too early too tell?? I’ve been cramping a lot but not really sure if I should wait another week to take a test... Can I be pregnant and it be too soon to tell?? I’ve heard about it being too early but not really sure any help?!!
