please help!! thank you!

Lauren • My husband and I have two girls, a 6 year old and 2 year old! We`re pregnant with girl #3 💝💝💝
Umm...my step-mom put salonpas on my neck for me (not knowing I was pregnant yet, I'm not telling them until Christmas) anyway, how can I wash it off safely because I don't know if it's okay to use while pregnant?
