I understand your concerns.
For some reasons, your intestine is not contracting normally producing normal bms.
This can be due to the change in water, food and also increased stress level.
Slow intestinal motility will cause thin stool or very large stool.
Reassuring point there is no blood in stool or black tarry stool which could have suggested more ominous.
Type of dietary fibers plays a vital role.
Insoluble fibers like methylcellulose is better.
Starting a probiotic like Culturelle daily will help.
Reduce fat intake, increase dietary fibers, and moderate proteins.
Now you can see your doctor for abdominal xrays to rule out any bowel obstruction.
But still it does not sound serious since you are still having bowel movements without any blood, or loss of appetite or stomach pain.
