I had sex drunk with a guy who did not use protection but then later on did but he didn’t come inside me.

But as we all know nothing is 100%

So I took a Plan B the next morning and went on my usual day nothing strange happened I had a small bleeding after that week but now I should have gotten my period.

The pharmacist did say that my period would come later and it is later and I took a pregnancy test and it was negative but now I’m scared I might be pregnant even though I don’t have symptoms I just want to be sure what’s happening because now I’m confused.
