how can i get some?

so my mother won’t even let me bring up the topic of getting birth control. and she doesn’t know i’m sexually active. i have protected sex but it would make me feel more comfortable if i was on birth control. but i don’t know how to get it without my mom finding out. i’ve already had one pregnancy scare and i don’t want another, so if any of you girls can help a sister out. please let me know💕💕
