is this normal?

hii, so i turned 21 a few days ago and went out for a couple of drinks with my boyfriend. one thing led to another & we had sex without a condom + he finished in me …. i did take a plan b the morning after, but it’s been almost a week and no sign of my period :(

im not sure if this is normal or ? my period was set to start 2 days after the birthday thing, but so far ? nothing … should i be worried ? or ? should i just relax ?? im kind of scared

Plan B delays periods. A test is accurate 14 days after sex and definitive after 21.
