I was tested when I was about 4 months pregnant with my son, I tested positive as a carrier, my husband tested neg. My son who is now 2 has had many problems with constipation, even been in the er for it, he had RSV when he was 1, and now they have dianosed him with asthma, I asked the dr. last wee about CF she said that if he is a carrier of CF he might show some syptoms of CF, has anyone heard of this happening? My son has always had thick mucous, a cough, bowel problems. I wonder if my husband should get tested again? Any help is appreciated!!!!
