I've had this on and off since 20 ish weeks (now 33wks) and been tested for anaemia, I was, been taking spa tone and iron levels have risen but this week in particular I feel SO unwell with this heart issue. It wakes me up at night and I feel exhausted and breathless just unpacking a dishwasher let alone going upstairs. GP says nothing to worry about but I feel rotten :( anyone else had this and any tips? Maybe in just over doing it? Two DC age 5 and 3 and DH works 6 days a week.
