Late period

Miranda • Mommy to the sweetest little man 💙

So I am on the pill and this past month I haven't taken it correctly. I get off of work and I'm so tired that I just go to sleep and forget. My period is supposed to come today and I have felt nothing like I'm supposed to When it comes. No Back pain no cramps nothing like that. My boyfriend and I have sex regularly and he pulls out every time. Should I be worried about pregnancy?
