Dad ALMOST finding out my stick n poke tattoo

Hello. I’m 17 and I have a stick n poke tattoo of a heart on my finger. I honestly regret it. It was at a sleepover with new friends and I got a stick n poke tattoo with no hesitation. I never even planned on having any tattoos on my fingers, it was at an exciting moment, I just didn’t think. My stick n poke tattoo is a year old and I plan on having it removed in the future. One of my friends work with my dad at a car dealership and they were talking about tattoos. According to my mom, he asked my dad “doesn’t your daughter have one” and he’s like “not that I know of? I hope not.” Something like that. I turned white. Fuck I’m even shakey from typing this, lol. Surprisingly, he was acting normal and still is acting normal. My mom, my sister, my brother, my bf, friends, and I are the only people who know. My dad and his side of the family are the only people who don’t. I also planned on MAYBE telling my dad about it in the future to help me pitch in with the money I’m saving to get my tattoo removal done when I’m like 19 or 20. Or i can just do that when I get a job after graduation. The problem is... he discriminates tattoos. He’s from México and where he grew up, tattoos are gang related and only cholos have them. My dad and i aren’t very close either. When he would hear me talk about wanting tattoos, he would say he’d kick me out. I know what I did wasn’t okay, and I’m already learning my lesson with regret and sleepless nights because of this tattoo. I can’t even sleep peacefully with it. I’m scared of him making my lesson more terrible like forcing me to end my relationship and not to hang out with my friends anymore or maybe kick me out or worse, disown me. We may not be close and whatever but I don’t think I can handle him disowning me. I admit, I made a mistake and I hope he can cut me some slack and understand that it really was a mistake. I want to be prepared for what’s coming from my dad though. If my dad gets a hunch or something about me having a tattoo and asks me about it or force me to reveal it. I can’t relax. I’m scared of that day will come. Can anyone give me any advice on confront a parent about their tattoo or a story that ends well? Any outside opinion, advice or a story would be nice. Thank you ❤️
