Cat scratches while pregnant???

Jaime • I am 22 and my husband and I are expecting our first child. We are to welcome in a little boy in November.
I am currently 18 weeks pregnant and my cat scratched me. She got my chin pretty good. I cleaned it with rubbing alcohol and put triple antibiotic oient on it. Should I be concerned about it. I remember hearing that it was dangerous to get scratched while pregnant.
