PLEASE HELP! Recommend a pregnancy test.

I think I might be pregnant as my period is 7 days late & counting, I feel nauseous occasionally but haven’t vomited, I’m having mood swings and experiencing lower back pain.

I want to take a self pregnancy test but don’t know what brands are trustworthy and what aren’t. Am I better to go digital for the extra money or are the non-digital ones just as good?
