Hi, My Name Is Preeti And I'm 23 Years Old.

Hi, My name is preeti and I'm 23 years old. I had sexual intercourse with my boyfriend 3days ago. And we found out that condom broke during the process (anal) and was left inside the anus. Although i couldn't feel anything inside me but my boyfriend was quite sure about it. Also i tried to remove it with my fingers but couldn't find it and also don't think it got execrated next morning or day after it. I'm worried if it's gone to some other parts inside and might cause any problems? What should i do?
