Possible pregnancy?

okay so I had my period July 3rd-9th and then had unprotected sex on July 13rd. I took a plan b right after and he also pulled out. He did his business on me so I know he pulled out... having sex was not our plan... it kinda just happened and I stopped birth control 2 weeks before and so I rushed and got a plan b just in case... on July 20th I started my period again for a week but I was suppose to start on August 1st... i have white creamy discharge too but I’ve been having cramps. I haven’t started but I had 2 periods in July.... my stomach is sore but I am a cheerleader so it could be from that but I’m bloated and kinda scared... opinions? I know there is a possibility but I feel like it’s unlikely because he pulled out and I took a plan b...
