Thank you girls so much I really needed and advice :)
That's bile (stomach acid) and yes it's foul. My m/s was so bad that I was throwing up stomach acid. It won't harm your baby. Try to eat and drink plenty.
Its bile. It happens when there is no food in your stomach left to puke up. I know it sounds like the last thing you want to do but try to eat something.
That happened to me twice already. .I was told that it happens when your not eating righy.. I believe it's called bile.. look it up! It's normal
