I'm a day late

Carol • Mother to 2 lovely kids Liam age 9 and Penelope (Penny) age 1 , also expecting baby number 3 due September 2016 ! 💙💗
as the title says I'm a day late . I ran out of HPT's so I peed in a cup this morning with FMU so I can test it when I get HPT's soon from the shop haha . I'm so nervous to test I feel sick . I can't bear another bfn . I tested at 10&11dpo and bfn . Today is 14dpo so I know I'll get an accurate result if I test today .
​Had a slight temp rise this morning but I'm feeling that it will be a bfn . 
​Do I save myself the heart ache and wait to see if AF shows or do you guys reckon I should test anyway ?
