R@pe kit

I’m contemplating getting a r@pe kit done..but I had some questions about it maybe someone here could help me out on. I’m just incredibly nervous about even the thought of it but I feel like it would be the best decision to do it. I’m in a lot of physical pain, cramps, and a condom wasn’t used so there’s a chance of pregnancy or an STD😳😨. So I was wondering first of all how to even go about it, so I just walk in to the ER or is there like special hospitals. If anyone went through this how was your experience? Like were the dr’s nice, was it painful, how many dr’s are in the room, and how long did the whole process take? Obviously I’m very anxious, and already hate going to the doctors as is. Also are you aloud to bring someone in the room with you, I feel like I might want to because I’m super nervous but also that might be awkward idk.. I’m also a minor though and pretty sure that means their going to have to alert authorities which is dreadful but it is what it is I guess, probably for the better anyways..
