Changing Obgyn???

Has anyone had a problem with their obgyn? My obgyn seem as if he's doesn't have a care about my concerns. I feel like many of my questions I ask him gets brushed off. I feel like a number with him and it's not just my hormone talking. Thinking about changing obgyn but wondering can I since I have been seeing him since finding out I'm pregnant. Currently I'm 11 weeks and 6 days!
