4 days late? Negative test?

Allison • Pregnant

Anyone else having this problem?

My fiancé and I have been trying since august, I’m now 4 days late... my nipples feel like straight sandpaper and super full, cramping, loss of appetite, diarrhea, insomnia, all the freaking above and all negative test!!!!

Is there a way my bodies hCG is just too low to detect?
