Dizzy spells

I’m 13 weeks pregnant and was hoping the first trimester symptoms would start to subside, but recently I’ve been getting very dizzy, disoriented, and headache-y on a regular basis. It’s the worst when I first wake up in the morning or from a nap, I have to get up slowly. I’ve been drinking a ton of water thinking maybe I’m just dehydrated, but it doesn’t seem to be helping much. My blood pressure today was 138/87, and I’ve heard having a pulse pressure (difference between the two numbers) over 40 is not good. There’s also been blood in my urine the last few times I’ve been in for my OB appointments. I also have a 15 month old son I have to take care of so this is impacting my day to day life pretty badly.

Is this normal at this point and does it go away or should I be more concerned? I feel like I have a constant hangover.
