I'm 34 weeks pregnant and I'm wondering if it is normal to feel so drained that every 5 mins I have to sit down or just lay down. I try to do housework and I get so breathless and puffed out, literally. I also have DS (3) who I try and keep up with. I just feel anywhere I am, I could curl up and rest. It could be I'm unfit or it's the heat. I don't remember feeling this exhausted when I was pregnant with DS and I worked right up until 38 weeks with him.
