Fertility testing

OneandOnly
Anyone here been trying for over the year and seeking medical help? My husband and I just met with my obgyn  after trying for 17 months. We have total faith in God believing that He is the one who instituted the family in the garden of Eden and commanded children when he said "be fruitful and multiply." We just believe He has given certain people wisdom and knowledge and expertise that we just don't have and therefore there's bithing wrong with seeking medical help. We were recommended to get semen analysis for my husband, and blood work, hsg dye testing and ultrasound for me to be sure my tubes aren't blocked. She said a good percent get pregnant after having this test done because it helps to unclog minor blockage that could be preventing pregnancy. Anyone have experience with this or success after having this test done? I believe God has this all figured out and am excited  for our future family:)
