help!

period in 3 days, been having very wet and white discharge and have been cramping on and off for about 4 days. i don’t think it’s implantation cramping because i haven’t had any pink or brown discharge and the cramps have been getting stronger as i get closer to AF. no sign of my usual pms symptom of tender breast but i have been having mild nipple pain. i constantly have to go to the restroom as well, i just started getting sexually active but we always use protection from beginning to end the only difference this time is i let him finish inside with the condom on, there were no tears, rips or breaks or leaking and we had sex about 1 day after i ovulated yet i’m still stressing
