Hello mummy. Don’t worry it’s normal. Don’t apply anything either. I have the same symptoms and I get like a ergonomic seat thingy for wherever I sit. It works to relieve the pain temporarily - at least I get to sit comfortably. Good luck! https://backjoy.com.sg/products/sitsmart-posture-plus-2
Better not apply any medicated oil because it may trigger contractions... Lower back pain is normal if tolerable like you said its only mild but if it is too painful better to consult your ob-gyne...
If mild should be ok but I will still let my gynae know. And I will also not apply medicated oil since it penetrates through the skin. Use hot/cold compressor instead
if mild it's normal at about 18 weeks my back start to sore at times prenatal massage helps alot
Please let your gynae know
