I m 25 weeks pregnant. I m having cough and i split out white mucus. Last one week i had this thisvissue and day by day i m feeling recoverng without any medication. Today i feel much relived and not much coughing. I had wheezing problem back 4 years. Will it affect my baby? I dont have any other symptoms of fever or eye pain or body aches. Should i need to undergo swab test? Adding, when i was trying to hear my heart beat and breathing with stethoscope in morning i was perfectly normal. Last week at night i heard some whistle sound while breathing . But not n morning time. Should i need to be concerned?
