Strict Parents

I lost my virginity a couple of days ago, I'm 21. I would like to tell my mom, but I feel that she would judge me and tell my dad. My parents are both very conservative Christians and having sex before marriage is a huge no no. To give a little background on my parents, they hate me wearing tight clothes. They believe it's disgusting and I am just trying to make guys look at me, they also believe its vey slutty. The only thing that I wear tight are jeans. I would like to tell her because I'm her daughter, but I don't want to be judged or yelled at, especially not right now at this point in my life. What do you guys think?
