It's morning sickness. Your puking stomach bile. I puke every morning for 9 months.
I do the same thing! I have since the beginning and it still happens. I'm 22 weeks. And its acid that is coming out. Bleh!!! Most disgusting taste ever!!!
Thats the only time I ever git sick and it was due to morning sickness
I feel like that when I first wake up sometimes too. I try to eat something and that usually helps.
