Cramping a week before period

Hey so I have been experiencing light to mild cramps and this has been going on since 7 days before my period. Is this normal that I am cramping a week before my period? I wouldn’t be pregnant right? I had sex 5 days past my ovulation and fertile days. Would this be implantation cramps? I’m not spotting or bleeding. I just have a transparent and odorless discharge. What do y’all think? Does these cramps mean I’m nearing my period? I’m on day 3 before my expected period. Thank you :
