Does anyone know if you can use a pain relieving patch during pregnancy? (like an icy hot patch) I'm currently 20 weeks

I used icy hot on my back and hips throughout my whole first pregnancy

I was told no because there is an aspirin like product in the gel

Ive heard u are not supposed to use during third trimester cuz it can cause complications. Not sure about first and second trimester.

I heard no

my doc told me I could use icy hot and I checked the ingredients and they are the same
