the pill

is it normal when missing 2 birth control pills you spot and don’t get your period? (I couldn’t get my pills on time from pharmacy) I am 11 days late now and it’s been 11 days since i’ve missed those pills. i’ve also been taking the pill back up for a week and a half and still no period. i haven’t had send since january 12 and got a pregnancy test 2 weeks ago and was negative.
