Help!

Hiya! I'm new to this site. And I'm in a bit of a pickle I guess. I'm 19 years old and I'm going to be put on birth control for the first time. I've did my research, and I'm totally not okay with things going up my lady bits. Yes it's good and such, but it's just not for me. I've been told that if I have really bad side effects, then I'll have to change it. I just get stressed out about how ill react to it. So, my question is what's worked for you or what do you suggest? Thanks!
