Helpp I'm freaking out Idk

So I had protected sex about 3 weeks ago and I googled it because I was nervous I'm still a virgin but I haven't had any spotting or any pregnancy symptoms. But my period did come 2 days early and I googled implantation but there's no spotting my pad gets filled with blood it doesn't stop for an hour and it's been like that for 3 days I'm going to day 4 but I noticed clots which is regular in my period but I also had cramps the first day . Do you think I'm pregnant? I'm going to the clinic tomorrow but I also been looking at abortion places and stuff . Idk what to do I'm freaking out but I'm just trying to stay calm and positive
