8 weeks & feeling like 💩

So with my last 2 pregnancies, I felt amazing the entire time (both girl) No morning sickness, no headaches, no nausea.. literally nothing but weight gain! Hahah. This time around with baby #3, not so much. I’m fine as long as I’m sitting or laying down, but the minute I get up, I’m nauseous and lightheaded and feeling like complete crap. I feel like 9+ hours of sleep still isn’t enough. I’m EXHAUSTED. Is anyone else going through this right now? What are you doing to make things better?!
