Others down playing your pregnancy

Does anyone else experience other people down playing your pregnancy? I'm 22 weeks and 3 days and I have an obvious bump. I don't look 40 weeks pregnant of course, but it's pretty obvious. Any time in speaking with two family members in particular, it always "you're not even big" or "oh just wait until you're further along, you haven't seen anything yet". Why is it necessary to make me feel less pregnant? This is such an exciting time for me and I'm enjoying my pregnancy but I feel like people always have to down play it! Maybe I'm just being too sensitive. Thoughts??
