Just stress or pregnant?

Supposed to get AF on April 6. Usually I am right on time or a day early. AF has always been normal and it's always the same. Boyfriend and I have always used condoms or the pull out method. Am I just freaking out or could I be pregnant? Trying to be patient and wait a week or two before I test so I don't freak myself out. Been super tired lately, I'm sore, and my boyfriend noticed I seem bloated. Also lots of acne. Any advice? Thanks.
