Ferber method sleep training

For moms who have done Ferber sleep training, how long did you wait to go back to sleep yourself after your baby did? My daughter fell asleep after 3 minutes but I’m afraid to go back to bed and have her wake up and need to start all over 😩😴

Edit: I waited until she was asleep for 10 minutes and as soon as I laid down in bed she started crying again.
