Bad gallbladder?

So I had my son 16 months ago and ever since then i will sometimes get this horrible stabbing pain in the upper part of my stomach that sometimes radiates to my upper back. (sometimes it causes me to not be able to move bc of the pain) and I get nauseous often. I went to the hospital the 2nd time I had this pain (about 10 month's ago) and they just did a urine test and ultrasound and said they found nothing. Starting recently I will get a pain in my upper stomach thats not as bad as the other pain I sometimes get and usually if I take and antacid and/or eat it helps the pain.. For you ladies who had a bad gallbladder/gallbladder removed does this sound like mines bad? I can't afford to see a doctor and will only go to the hospital if I absolutely need to.. I'm just so tired of dealing with this.. Ty
