Annoyed by colleague

I'm 15 weeks today, but not really showing yet. Today, in a team meeting, I brought up the issue of how to tell my patients and finding coverage for them when I'm on leave. Most of my colleagues were supportive and helped me think through my cases. But the one colleague who I'm actually closer with said, "you don't look pregnant at all... It's 5 months from now... Let's wait to discuss this later." I mean she's technically right, but I just felt so invalidated and dismissed. Like, you're not even pregnant enough to be talking about this. I also know she has been TTC and struggling. *sigh* guess I just wanted to vent to some people who might understand.
