Feeling disgusted!

Hello ladies. This is my first pregnancy and I'm 7 weeks and 4 days, I'm having an issue with being able to eat anything. Everything I eat and even crave if I go to eat it immediately I feel disgusted and I start gagging resulting in not being able to finish my meal. I have lost weight rather than gain and I don't have my appointment until next week to be able to ask my doctor. I am drinking plenty of water daily so that isn't an issue. Thank you in advance!
