My FEV1 was 80% when I got pregnant. We did it naturally, but it took 13 years. Also, I thought my FEV1 was fairly high and then while pregnant it got down to 46%, so not everyone with higher FEV1s do better when pregnant. Thank the Lord my FEV1 popped back up after my son was born though. <img src="i/expressions/face-icon-small-smile.gif" border="0">
