this is typical 8th month symptom. breatlessness will go away in few days/weeks when the baby leaves space from upper tummy and goes more in the abdomen. its head gets engaged in pelvis so u get eased out from top and get relieved from breathlessness and u will also feel more hungry

It does happen. But pls inform your dr. Adjust your sitting position too. That helped me. At the end i sat more upright.
