Hi, I am 23 weeks pregnant with my 4th and I've started to feel very breathless and getting dizzy spells. My bump is very average in size. I've had huge bumps in my previous pregnancies with excess fluid and never felt this breathless until late in the third trimester, I'm not at that stretched/no room left stage. I have a bmi of 22 and I'm active and healthy, in my early 30's. I've never had breathing issues/asthma. I just don't feel like this normal, I'm eating well and its not happening as a result of me being over active, I can just be sitting or standing and I get waves of breathlessness and feeling disorientated. Any ideas why? Should I see the doctor or the midwife? I last saw her at 16 weeks and not due to again until 32 weeks apparently but I don't feel right at all.
