Telling my dad I’m pregnant!!!!

2 weeks ago I confirmed that I am pregnant, I am 9 weeks now. My boyfriend and I basically just knew but we finally took a test and I am definitely pregnant. We have been together for 4 years going on 5, I am 22 (gonna be 23 in July) and he just turned 25. My boyfriends family is super chill and laidback and supportive for the most part and then he’s not super close with his dad, he has a better relationship with his stepdad. My bf and I decided to not tell anyone until the first trimester ended since we decided we want to keep it but he ended up telling his mom which is cool so I went and finally told my mom to make it fair. Both our moms now know but my mom is emphasizing how much I need to tell my dad, me and her talk about it when we can since my dad is under the same roof and he doesn’t know. My mom had a calm but shocked reaction, she was upset just bc of how young I am but she understands this is apart of life especially with having a boyfriend so she is honestly coming around and I’m very appreciative. But I am sooooooo terrified to tell my dad, I can’t even gage his reaction hypothetically bc he’s pretty unpredictable but I know he’s gonna be so upset. I told my mom that he’s going to chew me out, and scream at me and berate me but she doesn’t think so, she just thinks he’ll be upset for a few days and probably not talk to me for a day but I don’t know. I wanted to have my boyfriend with me when I told him but my mom says she’s not sure about that and she said she would also be there with me for support to tell him. I want to be able to tell him soon but my boyfriend wants to wait until my first trimester is over and my mom thinks the sooner I’ll tell him the better plus she feels guilty knowing about it without him knowing. Any advice on how to ease my anxiety about this? Can anyone relate when it came to telling their dad news like this?
