Early pregnancy symptoms?

I know I’m over thinking but I can’t help myself. I’m that girl who’s been taking pregnancy test starting 5DPO. I have major OCD. My period is due in 5 days and since yesterday I’ve been having light cramps and today the same + back pain. It’s more of an achy feeling vs actual pain also my cramps are not painful but achy as well. I’m nervous ima get my period early but hoping it’s a pregnancy sign?
