I was wondering about the way I'm feeling with my third pregnancy (25 weeks & 5 Days) Is this normal

Hello I'm 25 weeks and 5 days pregnant today and i had my blood pressure checked yesterday and it was 150/60, i was wondering if this is normal? I was diagonised with hypernemesis graviduim at about 8 weeks, at about 12 weeks I had to be admitted to hopital for 6 days.  every now and then i still can not hold fluids down like water or Gatorade. At times I feel like my body is shaking but it is not, and somtimes my head feels like it is spining so i have to sit still until that feeling goes away before i do anything. I also get really bad migranes that are so bad I do not feel like being at work or dealing with anybody or anything. I hope you can help me with some answers. Because I don't know what to do about how i feel sometimes. sometimes i want to go to hospital but i don't want to be germatatic or anything. My husband thinks being pregnant is so easy, but with my other two pregnancies i didn't have any problems. SO I'm so confused about why i feel this way.
