Nervous

So I’m 19. I have a doctors appointment with at Planned parenthood to discuss my birth control options! My aunt was supposed to go with me just because I hate going places alone, unfortunately she got the flu so now I have to go alone. Lol I’ve been once before but I had to cancel my actual birth control appointment. The birth control I want is the Liletta IUD does anyone have any advice about it? Thanks y’all
