Major bloating... pregnant???

So we’ve only been trying for one cycle but my period is 2 days late which honestly isn’t anything out of the ordinary it’s normally 1 or 2 days off from what the app says but I never ever ever have bloated before & now I’m feeling what other people who bloat all the time do!

For the past 3 days ive been bloating so badly!! I have a pretty small stomach I think (picture below is what it normally looks like)

But for a couple days it’s been huge! & I just feel like ive gained a disgusting amount of weight in like a matter of 3 days!! I just feel so uncomfortable because of how my stomach is pushing out. (Below is what my stomach has been looking like)

Is it possible that bloating is an early pregnancy symptom?? & that would be the only symptom I’m having? Or do you think it’s could just be a new thing with my period? Help!!
