4 days for period

I'm 4 days for my period. And I have a lot of acne, it's driving me crazy. On my face, back, breasts, neck. It's even between my hair on my head. Normally I have a lot of symptoms related to a pregnancy but then I found out I was not pregnant. And this month I was nauseous and had acne. Since a few days I'm not nauseous anymore. But the acne is more and more. I really hope this is the month with a positive test. But I doubt it. Did a pregnancy test just a few minutes ago, but it's a very faint line.
