Mama, I'm really sorry you're going through this, it sounds so tough, and I can hear how worried you are. Please see your doctor or go to the ER soon, lalo na if you can't keep any water down; dehydration at 11 weeks can be serious para sa baby at sa'yo.
A few of us moms have had really bad morning sickness, but what you're describing sounds beyond na, so you really need medical help to make sure you and baby are okay. Hindi ito something to wait out, doctors can actually help with this, so don't suffer in silence, sis. Hang in there, and please get to your doctor ASAP. Praying for you.
