fundal/high placenta = extreme breathlessness??

[Doublebubblebubble]

Hi all I'm 31 +2 and recently I've noticed that I'm getting very very breathless doing simple things... Reading my 5 year old DD a story tonight was like climbing Everest...smh

I'm sure it cant be because I'm anaemic as I've been on a course of iron tablets that I have to take 3 x a day, religiously, for a little while now and I'm generally feeling a lot better because of it... So I'm now wondering does having a high placenta cause/add to this kind of discomfort?? According to the last scan baby is head down but still quite high... And incredibly active.

Obviously I realise that the bigger he gets the more squished my diaphragm and organs in general are going to be - I'm just looking for other experiences really xx
