GERD, LPR, Asthma, 6 mos pregnant

Seager • 31 year old mother and wife. Expecting baby number two.
Anyone dealing with preexisting reflux and/or or upper airway issues? I'm almost 24 weeks and my LPR and asthma are really kicking up as the baby grows. I feel dyspnea nearly all the time when this happens and wonder if anybody has any experience with this? Thanks.
