Well i think this is the best place to post this im 34 with cystic fibrosis and had a possible miscarriage at 6 weeks. This is my second one in two years. So the dr is testing my blood to see if i may have negative blood my husband is positive so i may have to get a shot i dont know too much. I ttc for many years finally i broke thru and did it only to find out there is another block in the road lets hope positive info from the docs and that they can fix this.... we will keep trying. Thank u for all the support.
