Help!!

I am not on any type of birth control, but when I have sex we use a condom and pull out. I wanna talk to my mom about getting on birth control. she is very old fashioned and does not believe in sex before marriage and does not know my boyfriend and I are having sex. I want to get not just for sex, but little things throw my period off. like if I'm over stressed, start working out stop working out. Just little things will throw it off. I mean the extra protection for sex is nice to but I am more concerned with making sure my period comes regularly. How should I bring this up to my mom. TIA
