Could i be pregnant

Ok. So just let me say that i am regular with my period. Every time my app says im supposed to start i do. Well last month i was 6 days late. I am Very regular like always. And then i got my period for a couple days. Well this month i am also late by 3 days. Like i said i am regular. I havr no cramps or slight bleeding like i usually do before i start. I have sore boobs off and on and get nauseous sometimes. But thats it. Is it a possibility that i can be pregnant? Did this happen to any of you girls?
