Should I go to the ER or no

I been getting dizzy lately to the point i have to lay down and not move at all or I feel the whole room moving, sometimes I pass out. I had severe morning sickness in my first trimester now in my second one too, I read It was “normal”. But now I’m on my second trimester about to be 20 weeks and I been getting them lately pretty bad they are with pretty sharp pain in my head. I usually can handle any pain and headache, I have to suck it up because pain meds don’t work. Any ways I also have ear problems, hearing loss on my left ear having 30% hearing and in my right ear hear ok but i have to take care of it( change of weather, pressure, noises, etc.) so I’m not sure what cause of dizziness. My OB hasn’t worried about it and the ENT appointments are not covered in my health plan so I haven’t get checked lately. I was thinking of just going to the Er to get checked because im unable to do daily things and I have 2 daughters under 4 and they need me. What should I do? If just feels to much and I don’t know what to do.
