Impetigo? Or something else? Currently pregnant and anxious

[TwinkleTwinkleX]

My 3 year old daughter has a rash on her torso (nowhere else) just popped up today. Otherwise seems totally fine in herself. It’s been hot so wondering if it could be heat rash but there’s been a case of impetigo at her nursery so wondering if it could be that. She’s had the chicken pox vaccine.
im 38 weeks pregnant so extra concerned about potential effect on pregnancy/ newborn..
any thoughts on what it could be? Experience of similar? Will take her to gp / pharmacy tomorrow if not clear. Thanks x

I'm wondering if that's a mole (on side of stomach fussy photo) or possibly a herald patch? https://www.nhs.uk/conditions/pityriasis-rosea/

Oh yes maybe it’s a herald patch as it’s not a mole and came up first!
