hi - currently 24 weeks and really struggling and wondered if my symptoms were normal as with dd1 dont remember feeling this bad..basically feel out of breath and totally uncomfortable walking around for more than 10 minutes.. sometimes even out of breath when sitting talking - also my nausea has returned and after having test for low iron (all normal) am being to become worried what could be wrong with me - I was not overweight before becoming pregnant and have so far gained about 10lbs- anyone else feel like this??
