Am I pregnant?

Okay so my boyfriend and I have sex pretty frequently. And I’m on he pill but this past week I’ve slipped up on taking my pill by forgetting one day but I took two when I realized (the one for the day before and the one for that same day) and also forgetting and taking it two hours later when I’ve remembered. I usually get my period when I’m on the second week of my pill pack but so far I haven’t but I did bleed last month. My periods are very light. Although I did noticed a little bit of bleeding about two days ago but it was very minimal. My nipples have been feeling tender and I don’t know what’s been going on?
