I’m currently 23 weeks pregnant. I have noticed when I’m doing tasks such as cooking, cleaning or going out to the store. I start to not feel good. My heart will start beating fast and will have a hard time breathing. I get dizzy and feels like I’m about to faint. I start feeling my forehead getting hot and start to sweat. It has been happening for a while now. I’m very concerned and don’t know if this is normal. I just moved from sea level to high elevation two months ago I have no idea if that has to do with this. Does anyone know or experienced this before?
