Upset

We have been trying for 3 months or so and this month I got really excited. I missed my period. Taken 10 tests 4 different kinds. All are negative. I am now 9 days late and kinda down bc I still have a negative test. My son took 6 weeks which is 14 days late to show a faint line. I'm hoping I am pregnant but don't want to get my hopes up or my husbands. I am usually regular between 28-31 days. I never miss a month.
