Wanting opinions....

So a little back story. I am currently pregnant with my beautiful rainbow baby. My husband and I are over the moon. Almost eleven weeks. I currently attend college mon-thurs 9:10-12:20. I went to my math class and these two girls where talking, as always. Super rude, super annoying, super immature. Always talking so no one can hear the lesson, always talking about how stupid and ugly random people are etc. Anyways, i sit down at my table getting ready to take notes, when i overheard one of the girls. "Did you see Tasha's web history? It was all about IVF. Like how much it was and everything." And started laughing i saw red. My response. "Excuse me, i'm confused on how that's funny." "Well she already has a baby, so if she wants to get pregnant she can." Me: "So ur her doctor?" "What?" "Well you're obviously her doctor to be making medical opinions right?" She called me a bitch. Which I reminded her it's neither funny nor cool to make fun of a woman who wants a baby so bad she belong to spend tens of thousands of dollars to make that happen. She called me a bitch again, to which I reminded her that she doesn't even have custody of her son and to make such asinine statement shows her intelligence level. After that they started telling people at school if I wasn't pregnant they beat me up. Morons.
