Plan B messed me up?

Angel

I took plan b bc me and my husband were obviously active, I’d say about a week later I got my period. So I guess it’s safe to say it worked ? So fast forward to now, I’m 5 days late for my next period and I took a pregnancy test like 7 days ago and it was negative do you guys think I should take another or do you think my period is just late bc the plan b? HELP ME PLEASE
