Right sided pain daily?

I’m at a loss. I’ve had bloodwork, ultrasounds and all is normal. Since having my second daughter, around 6-8 weeks postpartum I started having right sided pain. Nothing crazy I don’t even need to take Tylenol or anything for it. More of a nagging dull pain. It’s my right side slightly higher than my belly button and sometimes radiates to my side and back.

I do have frequent IBS-D attacks but I always have. The only difference I’ve noticed is having frequent “looser” stools and they are almost always a lighter brown/yellowish color.

What could this be? I am 13 weeks pregnant so a lot of tests and scans can’t verify done right now.

I’m terrified of pancreatic or colon cancer.
