at this stage of pregnancy
it is a common problem to be a little breathless because the diaphragm (partition between stomach and lungs) goes up and the amount of air which can be inhaled in single breath is decreased. the hemoglobin
tends to be low and contributes to breathlessness, but still it is not usual to be so breathless that u start gasping. i would recommend to get your hemoglobin checked and do see your physician to rule out any heart disease
as incidence of heart failure
in pregnancy peaks up at 32 weeks only. i hope everything will be alright but still you must go for it.
try to rest on your side rather than on ur back. it will help to some extent.
