22 weeks pregnant and suffering with chronic bunged up sinuses- does anyone know if it is in the slightest bit allowed to have the occasional sniff of otravine or a night nurse capsule? I just read that olbas oil (my saviour to date) is contra-indicated in pregnancy. When it doesn't say "not for use in pregnancy" im never sure if that means it is safe, or simply unproven. Am willing to slightly risk the latter in return for some sleep!
