Too scared to test - advice !!

Carol • Mother to 2 lovely kids Liam age 9 and Penelope (Penny) age 1 , also expecting baby number 3 due September 2016 ! 💙💗
Hi guys I'm 2 days late for AF and too scared to test . Have been TTC 7 months now. 
​Usually I'd have tested by now but last month my AF showed up 6 days late (never ever been that late before without being pregnant) 
​I'm scared this month will be the same  !
​I'm scared to see a bfn ... TTC is making me sad when it comes to the waiting and bfn and AF after 7 months . 
​I am desperate to test and find out for sure but I'm so scared of bfn and getting upset again . 
​Should I wait until I'm say a week late and test or just go for it today? My OH wants me to ASAP
