TMI—Bloop in baby stool?

Hello. So this is the third time this has happened.. just wondering if there’s anyone who has experienced something similar.. Three weeks ago, two days ago, and today. She is 4 1/2 months and exclusively breastfed.

Side note I moved to Japan a couple of months ago to be with my husband and I’m freaking out that this happens as soon as I leave America :(

I don’t know what to do. I told the doctor here and he said it was fine since she doesn’t have any other symptoms but he didn’t even check her or anything :(
