I'M NOT 16 I'M 24 stop with the stares! ???

Kateennia • 24yrs old, first time mom, Full-time college student and worker. Very caring and loving.
Now that my belly is noticeable I get weird stares like, "look another teen pregnancy." I'm 5'3 and I actually look like a sixteen year old which in most cases a blessing. But now I'm constantly being judged like I am a teen. So what I say when passing by them is, " being 24 and pregnant is wonderful even though I look like a sixteen year old". Then they make a shocked face like OMG! It's annoying and disrespectful I hate it very much. It REALLY bothers me now. I don't know hat else to do to be honest, I just don't want to leave the house anymore honestly.
