Health Concern

So this is slightly embarrassing but I’m looking for advice. A couple months after giving birth to my daughter in November 2017 I started having digestive issues. There are many times where I would find myself running to the bathroom with no warning to either throw up or evacuate my bowels. I saw my primary care doctor who told me I had just given birth and my body was adjusting etc etc. Fast forward a couple months, things were the same but again I was told my body was adjusting, etc. Now over a year later things are much worse. There are times where I have “accidents” without even knowing I had to go to the bathroom, I have terrible stomach/chest pains, I am nauseous all the time, and have bad headaches. I feel like I have lost all control over my body and it’s only getting worse. I’m 33 years old, this shouldn’t happen. I’m tired of being wrote off by my doctors but don’t know what else to do. I feel like I can’t go anywhere because I don’t know if there will be a bathroom there or if I will have an accident. I don’t think it has anything to do with having a baby. It doesn’t matter what I eat, drink etc. I did have my gallbladder out in 2016, but I’m told this wouldn’t be caused by that. I don’t know what to do. Anyone ever been through this?
