What kind of charges can you get for assault on someone who's pregnant?

Ill be 18 in Nov. & im 5months pregnant, when I was around 2months this female (18years old) & I had gotten into an argument & it ended up with her spitting on me, pulling my hair, ect.. well of course I defended my self and put my hands on her also. She ended up letting go & started to argue with me again, well after all that she ended up leaving ( she was on my property ) . I wasn't hurt just had a few scratches, my mother wanted me to make a police report but I didnt want to cause I felt like it was just going to start more problems & I just wanted to leave it alone, i've had problems with her in the past with her harrasing my younger sister & I. Anyways she ended up pressing charges againts me ( assault & desrtuction of property? $250 worth damages ) I plead guilty to the assault but in self defence & not guilty to the d.o.p , she put in the report that I threw a garbage can or bike at her car! Like seriously im not even that strong & plus im not the violent type or even the type of person to do such a thing. Im going to trial in a week & they said I can press charges then which im not gonna be dumb about it this time & not press the charges, what can she be charged for assaulting me while I am pregnant ( she knew I was pregnant ) ? Just normal assault or ? I have NEVER been in a situation like this so I have no idea whats gonna happen or what not.. Im just curious, so someone please HELP ME OUT!
