What’s wrong with me?

I am 26 weeks pregnant with baby #2. The last few weeks I’ve been getting so..sick? Today, I got hungry, I started making my lunch & in the middle of doing that I got extremely dizzy. My heart & head started pounding. Started to get really shaky. Laid down on the couch I started feeling nauseas. Had to lay on the ground with my butt in the air, breathing heavy. I felt like I was either going to pass out or puke everywhere. Had to eat my lunch while laying on my side, on the floor & barely could even lift my hand to feed myself. 20 min after eating I still couldn’t sit up or stand up. Had to voice text my husband that he might need to come home, I barely had enough energy to speak. Luckily June baby was napping during all of this...

Am I anemic? Preeclamptic?

My clinic doesn’t open until Monday, & for obvious reasons want to avoid the ER. I have had episodes like this for the last few weeks just not nearly as bad as today’s. & my doctor said preeclampsia doesn’t start until closer to 28 weeks, I could be anemic but they don’t test until 26 weeks. That’s why I’m coming to ask you guys, already asked my doctor & they weren’t much help.
