Freaking out 😬

So I've been having white discharge the past 2 days and it felt like I was having my period but without the cramps. First of all, I had unprotected sex about 3 days ago and that's a week after my period ended and although he didn't cum in me I'm just really paranoid that I might be pregnant. Is the white discharge a sign of implantation or am I just overreacting?Â
