I'm getting fat in a weird way

I've had countless times where I feel pregnant but end up wasting money on pregnancy tests. Usually when I get fat I get rolls and fat on my sides but now its just a big round tummy. Can I start to show if its only a month or am I just fat? (there isn't really money to waste if I'm wrong)

My period is 14 days late but it is normal if it skips a month for me.
