NO HATE COMMENTS: abortion

So I have an abortion scheduled for this after considering my options long and hard. I am only 20, my boyfriend left me (not knowing I was pregnant) and recently lost my job. I can't afford it at this time. And the father and I decided this is best. Anyways, I was wondering if anyone has had an in-clinic abortion. If so, was it painful? I'm also worried about the shot in the cervix.
