Beat friend being mean about choice :/

I took a pregnancy test at the doctors today because a few weeks ago i missed pills and had unprotected sex. And i told my best friend that if i am pregnant i know what im going to do which would more than likely be abortion as i have told her in the past that this is what i would do if i were pregnant at this time. Anyways after i said i know what i would do she said....... What? Kill it? I was like really...... She then said she was taking the piss. I got really hurt by it and tbh im so disgusted. How would you guys react?.
I am by no means trying to start an argument about abortions. Just asking on how you would feel if your 'best friend' said this.
