My "friend" came in me without consent

First things first I'm aware that this is my fault too for agreeing to have unprotected sex on the basis that I thought I could trust this person. A few weeks ago my friend and me had sex. He was made aware that he wasn't allowed to finish in me after he asked if he could. Anyways, last week I noticed that I was a few days late, and that's when I found out that apparently he came in me anyways and just decided not to tell me. Once again I'm going to emphasize that I know that this is my fault before I get attacked 😂 anyways I told him that I needed to get tests bc I'm late. He completely disregarded this and instead has just been saying things like "you better not be pregnant" or "you better just be late", which I told him to stop bc it sounded threatening to which he just never replied to that either. I'm honestly just more upset over the fact that he waited so long to tell me bc we could've just gotten Plan B had he told me sooner rather than later.
