Side effect? Or should I be worried

I've been on Zepbound since May and I've lost 39 pounds a of today. I am currently on 10mg and have been on 10 since August. When I first started taking 10 I would get nauseous after every shot but it only last for about 1 day. That stopped after a month of taking it and I've been fine since until recently. About 2 weeks ago I had some food that really upset my stomach. I am prone to stomach pains my whole life so I wasnt really worried. From then and for about a week I was nauseous and could barely eat. I started eating bread to soak up whatever was in my stomach, which is horrible because I hate eating just bread. Now the nausea has stopped but instead I'm just in pain every time I eat, like stabbing pain. At this point I'm only eating once a day and only rice and eggs - rice cause it makes me feel better and eggs for protein. I'm still getting stomach pains but just not as bad. I'm not sure if this has happened to others? Maybe that food that I had that originally got me sick is still inside me? My doctor is just going to say it's a side effect which is why i haven't gone to him yet. I apologize for the long story just felt it was essential to know everything.
