I'm 36+3 with dc3. I had low iron (93?) and have been on tablets for nearly two weeks, definitely feeling less tired.
However, I get so breathless, even when doing very little. I feel like my heart is doing funny things, not alarmingly so but odd feeling. Like extra beats or missing beats, and my chest feels slightly tight. I almost feel like I've run around and can't quite get enough air, though I'm not puffing and panting. I seem to do lots of big sighs. It's hard to explain, I don't feel terribly worried but not sure if this is normal - I think I remember similar with my last two but not sure I felt this incapacitated! I am doing too much though, could be my body saying slow down!
Anyone experiencing similar?
