My guess is that this has something to do with your pregnancy and the fact that your nose is hyper sensitive right now.
Try again later.
That was my experience when I was pregnant too.
Maybe try to find a place that sells naturally scented (with essential oils) goats milk soaps... and give those a sniff.
They will leave a very, very light scent on your skin that might be more tolerable.
Smelling the EO's from the bottle in extremely concentrated form cam be overwhelming to anyone and you probably won't be able to tolerate this approach until your senses calm down post pregnancy. And even the premixed perfume oils are heavier/more intense smelling than most regular perfumes, only requiring a small dab to last a long time.
