Stressing out!

Hi everyone! My husband and I have been TTC for awhile now. I've been tracking my periods every month and have been pretty consistent even though I have a 35 day cycle. Well I am now 7 days late for my period. I'm not sure if I am pregnant as I am not having any pregnancy symptoms.  To be honest, I'm pretty scared to test because I just can't handle another negative test. :( Its so heartbreaking. Is it normal not to have any symptoms this early?? I'm worried!
