Used Human Shampoo On my cat..

I gave my cat a bath because we suspected she had fleas after my boyfriend came to visit, i use human shampoo as a thick ring around her neck because we didnt have any dawn dish soap, then i used a feminine wash to actually wash her fur. I rinsed her off multiple times in the first bath, dried her off, then rewashed her (but she wasn't fully dry for the second bath)

I looked up using shampoo on cats and i saw that it can be fatal for cats if they lick it off their fur? Will she be okay or will i have to seek vet service?

(no fear mongering im 15)
