Please help...baby ate paper

I feel like the worst nom ever. The baby grabbed a piece of paper and apparently was chewing it while I fixed her brother's plate. I only noticed she had it because I heard her choke. I was able to get 2 little pieces out of her mouth but theres a chunk of paper gone and unaccounted for. Should I call the doctor? Will it hurt her if she did actually swallow some? I can't believe I let this happen.
