My last pregnancy I had LOW blood pressure and had the same symptoms. My doctor told me they can only help if it’s high. I found the only thing that worked were the packets of pedialyte in a bottle of water! The strawberry lemonade one was the only one that I could tolerate but it’s worth a shot!! If it’s low blood pressure or dehydration it could help either way!
Yes these are common ❤️ I remember feeling this way my first pregnancy too and I didn't even have twins!
Maybe try more protein? Sometime so felt like that when I wasn’t getting enough fat & protein, I’m sure having twins you would need a lot more. I hope you feel better 🙏🏼
