Good morning everyone ☀️ Could you please tell me if it's normal for me to feel like this when I breathe, especially when I don't sit down or lie down? My head is spinning, I get sweaty, and I feel like I'm going to faint (like fainting). This has been happening for the last three days. I haven't felt this way during my first pregnancy.
