The good side here is that your agent will be paid through the seller's commission. If the seller will pay 7% commission, then the buyer's agent will get 3.5% of that. But, in some rare cases, buyer agents will attempt to get the buyer to pay the commission - don't go that route. Whoever you chose to be your agent may ask you to sign an agreement saying they are representing you - that is okay. Just make sure that the agreement says they will get paid through the listing agent's commission.
