Poss preg w/ gallstones. ADVICE?!?

So my husband and I found out that I need to have my gallbladder removed. So we decided to wait on attempting to add another pair of baby feet to our family.  Well, this weekend... Sh*t happened, and well i was around my FW according to my tracker.  Meet with the surgeon tomorrow for possible surgery, but can't officially test for another week and a half. Advice??
