One side supply

My newborn is now 8 days old. She started the first few days having a side preference for my left breast. I had to pump the right to be sure my milk would come in. my milk came in and the right was very full and firm since she was only feeding on the left. So I kept pumping my right. Around day 6, I was able to get her feeding equally on both sides. Now my right side (the side she used to not feed on) does not seem to be filling back up with milk ever since she emptied it and the breast softened.

Will the supply replenish? I'm worried.
