Am I pregnant please help!!!

Had unprotected sex (April 24) 2 days before my period was due (April 26 was when it was due) now I’m currently 5 days late 😩🙄😮? I got overly anxious and took a test 2 days ago and of course it came back negative and I’m sure that’s due to taking it a little too early or maybe I’m just stressing for no reason. We use the pull out method he swears he pulled out and he knows I’m not pregnant but now he is overly protective and keeps saying be careful you are my queen and you’re caring royalty it’s like the switch went from him knowing I’m not pregnant to him feeling I’m pregnant. I’ve been having lower back and stomach pain, been feeling very faint, and the day after we did it I whip after peeing and it was very very light pink and the same thing happen 2 days again someone please help.
