9 days late? Plz help.

Okay so, my period has never been late besides one other time. But only by 2 days, I usually have a 26 day cycle and I’m on cycle day 35. I have been getting light cramps but usually my cramps are pretty bad. I have mood swings like usual also, but I’m worried I might be pregnant. I have no access to a test because I am a senior in high school, my dad is a preacher and my mom is super christian and would be so dissapointed if they found out I bought one and I live in a small town where in the Walmart I go in, everyone knows my parents. So idk what to do... is it possible to get cramps and still be pregnant?
