Feeling rather crushed!!

Jenny
All day whenever I've sat down I've felt like my organs are being crushed - I'm only really comfy when standing!! 
Having just googled what the organs looks like when 20 weeks pregnant this diagram explains why I am feeling like this! I've not got much of a bump at the moment so my organs literally are being crushed!!
Anyone else feeling the same? I'm hoping my bump will pop and relieve this a bit soon!
