Am I or am I not?!?!?! HELP

So lately I’ve been experiencing odd things for example:

I can smell food that’s no where near me and I’m the only one that can smell it

I never ever get acne and I am breaking out and I’ve never broke out before

I’m super tired all the time recently even though I get a really good night sleep

I get irritated very quickly sometimes recently

What could this mean I’m 2 weeks until I get my period so I’m not late or a head I am sexually active with my boyfriends do we have been together for over a year now and we don’t use any type of protection besides the pull out method

Could I be pregnant?
