Hi, I'm 26yo and 21 weeks pregnant and had bad morning sickness up until 17 weeks, then I got gastro and the next week I got the flu. I expected to be better this week and actually start living again but I have found that I can't walk for more than 2 minutes without feeling like I'm going to pass out or collapse. I get puffed out, aches in my legs, my heart starts to race and I get light headed. I sit down and it takes about 10 minutes for me to recover and get my heart rate back to normal. I constantly feel exhausted and tired and sleep really well. I have been to the doctors and my blood pressure is fine and iron levels good, so I'm not enaemic. Next week I will have a heart monitor applied for a week because the doc wants to rule out a heart condition (I've always been perfectly healthy and never had heart problems). He said if that's not it then it is probably anxiety. I think that's a load of BS though as I have no reason to have an anxiety attack every time I stand and don't have any stress at the moment or feel anxious. I think it's just the doctor copping out because he doesn't know. Has anyone else had any symptoms like this during pregnancy and had it diagnosed?
