Laparoscopy with no signs of endo

So I just had my first ever laparoscopic surgery to diagnose endometriosis... Only they didn't find any. So now I have no idea what is causing my pain and I am feeling very discouraged. I've had pain for 3 years, ever since I gave birth to my twins back in 2018. I'm talking very strong cramps that come out of nowhere and at the most unexpected times, extremely heavy periods, painful ovulation, painful sex, excessive bloating...and my surgery found absolutely nothing. I have already seen a digestive health specialist and I DO NOT have IBS, and I apparently don't have endometriosis either. After all the research I did and doctors I talked to, I was really certain that I had it. And they didn't find anything. And so now I am sitting here, recovering from surgery, in pain, feeling defeated. I don't know what to do now and I'm really upset.
