Can you have HG without actually vomiting?

I’ll be 8 weeks with #3 tomorrow & since 6+5 I’ve had constant nausea. It never goes away. It’s there from the moment I open my eyes in the morning to the time I go to bed. It feels like I’m about to throw up at any moment but I never actually do (I’ve never really been able to vomit my whole life).

It’s gotten to the point where I’m avoiding food/drink because I don’t want to make the nausea worse. The only thing I’ve been able to drink without regretting it is Powerade (tried that to keep myself hydrated). It’s really interfering with how I go about my day too. Im a stay at home mom & it’s hard to keep up with my 3 year old & 1 year old when I’m constantly nauseous.

I’ve heard of people having HG but I know it’s mainly extreme vomiting in pregnancy.

I never ever got sick at all with my other 2 kids - not once. I feel like I’m definitely making up for 2 pregnancies worth of nausea.

I called my OB this morning, talked to the receptionist & was told the doctor wouldn’t write me a prescription because I’m “technically not her patient as I haven’t been seen for this pregnancy yet” (even though she’s the doctor who delivered my other 2). My first appointment isn’t until December 15th 😭

Can you have HG without vomiting? What can I do??

Edit to add: I said this before but maybe it was missed, I am physically unable to vomit, that’s why there’s no vomiting. I dry heave all day but I literally am unable to vomit.
