U need to go to the store and buy a pregnancy test and plan B. Plan B is a common birth control that should be taken after unprotected sex. If u take it, it will stop the sperm and the egg from meeting (however, if the sperm and egg have already met, it will have no effect and is still safe to take-the baby will be healthy). It stops the baby from forming, but if the baby’s already started forming, it doesn’t hurt it in any way. I hope you take this advice. Hopefully u r not pregnant, bt u gotta buy the pregnancy test and the plan B to make sure. It might seem awk, but u have to do it so u can know, don’t let one silly mistake ruin ur life. If u don’t want to interact with a cashier, u can try using one of the self-checkout options at Walmart.
