Hormones or intuition

I’m on the pill. Was a time I hadnt been taking it correctly which would’ve lead to my last bleeding 3 weeks ago. I have a few pills left (less than 5) until my next break. I don’t know if it’s the hormones due to my cycle starting soon or if my body knows something but I’ve been feeling like I’m pregnant. My breasts are slightly sore, I’ve been having unusual headaches, very bloated, feeling nauseous, and tired.
