for anybody that might be able to give some advice

hi ladies, im full of confusion.

im currently on the cerelle mini pill and have been for nearly 1 year. i know that they can mess with af but up until now the only difference is just lighter but still there right on time. however it was due on the 15th but iv had nothing. iv been feeling sick for nearly half the day on and off everyday, bloated, sore nips and i constantly feel drained. this has been for the past week.

iv never taken my pill late and iv never missed one so i really am lost. surely i cant be pregnant if iv religiously taken my pill everyday at the same time right??
