I'm scared

I'm so scared that I might be pregnant and idk what to do I really don't want to be and I'm no longer with the guy that it would be. I always use protection but he convinced me to try the pull out method and now I'm saved to death. I'm late my 6 days. I've been late before but I was feeling some dizziness and nausea a couple days ago if I am pregnant then it'd be about 5 or 6 weeks but if I'm pregnant from the very last time we had sex then it'd be about a week or two. Plz help me
