Surgery!!

Hi back in march before I found out I was pregnant I had a bad stomach pain which I thought I had the pain because I had eaten spicy food ! But I went into the ER to get check because I couldn't take the pain they and ultrasound and found out it was my gallbladder so they said I need it surgery, two weeks or maybe three weeks later I take pregnancy test and is positive so I wasn't scared I just thought that I could still get surgery I go back to ER and they said no you can't get surgery now I was about 4 weeks pregnant so now that I saw my OB couple times now he said I can have the surgery at 14 weeks but theres a low posibility of miscarriage I don't know what to do? I have some pain that comes and goes but nothing to bad. He said you can have surgery now or wait until you deliver I'm due date is December 27

I don't know what to do this is stresing the worse part is that I can't eat right because theres many foods I can't eat but then I have to eat I need advice or opinion?? Please I just feel that If dont get the surgery it will hurt later during pregnancy because it hurts now and im not go big im barely 11 weeks
