Baby’s odd poop colour

My 5 month old babygirl is currently on mixed feeding; direct latch at home and formula in infant care. Drinking Enfamil in IFC and her teachers commented that she kept pooping after/during her feedings today. After breastfeeding her at home this evening, she pooped an odd pale yellow (?) as in the picture. Can’t figure out if it’s an allergy or due to teething. She also just recovered from a cold over the past week. This is the first she pooped this colour and we’re quite concern. Any thoughts/advice? Will be heading down to see the PD tomorrow nonetheless.
