I’m 35+2 today and the last three days I have felt completely fine... and then BAM! Out of no where I feel like I get smacked over the head with some flu-like thing. I have gotten this rush to my head and I am super dizzy/faint, I feel super nauseous, a hot flash, my heart starts racing, and I’m very weak. It’s so strange. It’s like I could throw up and pass out at the exact same time. I drink water, sit down, and eat something, and I am ok within 20-30 mins. Anyone else experiencing anything like this? Is this normal or should I call my doctor?
