Pregnant at 21, advice please

I found out I was pregnant this morning. Supposedly 5 weeks. My mom has been supportive but has been heavily leaning towards getting an abortion. I obviously do not want to and she isn’t necessarily pressuring me but it feels like she thinks I really shouldn’t keep it. But I want to. The baby’s father and i aren’t together but we are very good friends and I know he would be present. And I have no judgement about abortions but I just personally could never do that. I know I would regret it forever. I guess I’m looking for advice on how to stand my ground and what other young moms did. How soon did you tell people? How do you keep it a secret until you’re ready? Did your family support you, etc?. Currently spiraling and not able to talk to anyone in my life about it. Thank you in advance
