TTC #3 but have a hernia...

hello all! My husband and I are ready to expand our family.  I have a small groin hernia from #2.  It does not bother me but I am nervous to become pregnant with it.  My doc says if I get it repaired now we can start TTC in 12-18 months.  By that time I will be almost 36.  I do not want to wait...anyone been through this? Thanks in advance!
