Stutter a lot when speaking Spanish?

Stutter a lot when speaking Spanish? I used to stutter a lot in English but now it's a mild stutter when I'm nervous or really excited (bad when I'm trying to roast 😥), but in Spanish it's horrible. I can barely say a sentence without stuttering. When I don't stutter though I speak fine. Spanish was my first language but I just speak/hear English more so maybe that's the reason. It's really hard to talk to my family because of that and they think I just "forgot Spanish" 😒
