6 days late, 2 BFN, recently quit BC...need advice please!

Any advice is welcome :) I am currently 6 days late on starting my period! I was actively on birth control until November when I stopped taking it. This will be my first actual period off of birth control in a while! I know sometimes they say after taking BC, it takes a little while for your period to get back normal! I have taken two pregnancy test with BFN... I kinda feel PMS type symptoms but no signs of bleeding at all- I am happily married and although me and my husband aren't actively TTC currently! We would be thrilled if I were to b pregnant at any time! Just needing advice on whether being 6 days late on my period is still considered normal after stopping BC....or could there still be a chance I'm pregnant even with two BFN! Thank you for all advice!!!!
