when to tell the father

C

Please no judgement, I feel shitty enough as it is...: so I’m pregnant from a one night stand 🤦🏽‍♀️ I am 4 weeks along. (Bc failed) I’m scheduled for an ultrasound in two weeks. I’m not sure yet that I want to keep this baby but I would like to tell the father and get his input at some point. Do you think the sooner the better or should I wait until after the ultrasound? What would you do? I’ve known this guy for years but i haven’t talked to him at all since we hooked up. Just looking for others opinions I guess.
