Is this SIBO??? please help!

I need some help please!!
I've had lots of health issues in the past year and no success in treating them.
It began with refluxing of food after eating, up to several hours after a meal. It has decreased since i went paleo, but still happens from time to time.
Additionally, i have lots of undigested food in my stools and most of my stools are loose and not formed, sometimes in a diarrhea like form. However, the interesting thing is that i also have constipation. My food moves slowly through my gut and tends to sit for longer than normal, meaning less bowel movements than i should have.

The most noticeable symptom is the feeling and audible noises of digestion happening. i can literally feel a gassy popping and get crampy, the kind of feeling you have when you know you have to go to the bathroom right away. its as if my body is trying to digest foods and cannot.

does anybody have any idea whether or not this sounds like SIBO? ive already been told a leaky gut, but a leaky gut protocol did not help.

i would GREATLY appreciate any and all help.

also to note: i have autoimmune thyroid disease (hypo) and no menstruation in a year
