<prompt> Human: First I want to preface this with I have never paid interest on a credit card. I pay them off in full every month unless I have a special financing deal and a special reason. I have 2 credit cards. One of them has no interest for 15 months and had a limit of 2200. The other has a limit of 800 and is what I use every so often to just earn points. I went to buy my spouse a new computer for 700 and wanted to put it on the credit card with the 2200 credit limit with no interest. I planned on paying it off in 2 payments. However because Im dumb and because both cards look exactly the same I used the wrong credit card when I purchased it. Its been two weeks and I now that Im going through my bills I noticed the money was on the wrong card. I maxed the card by about 120. I checked my credit score and it dropped from 740 to 640. I just paid the computer off in full on the 800 credit limit card. My balance is now where it was before. Im really worried this is gonna ruin my credit. Is there anything I can do?  <response>: Credit Utilization has no memory. Next month your score will bounce back to what it was before if your utilization goes back to normal. No need to worry.
