Pregnant

Hi so I’m 18 and I’m pregnant. I still live with my mom (i plan on moving out at the beginning on February). My mom has always been very strict and has always had a say in who i do or don’t date. I was dating a guy who was older and she told me she didn’t want me seeing him anymore because of the age difference but i continued to see him and now I am pregnant. Do i tell my mom (who is very judge mental and already doesn’t like my boyfriend) now or just wait until i move out in February?
