Am I over reacting?

I’ve been on the combined pill for about 2 1/2 months. I’m on my third pack and I take them like I should. Every time I have sex we use condoms.. lately my boobs have been feeling weird. Also, I’m craving takis (those spicy chip things) lol. Is there any way this could be signs of pregnancy? Or is it normal to crave things?? Please comment and let me know
