My husband and I have been trying to conceive for over 4 years and we have never used pre-seed. We are classified as "unexplained infertility" because there has been nothing found to diagnosis our infertility. We have had 3 rounds of clomid and two IUIs without success. I just bought pre- seed and we are putting medical interventions on hold for a bit- it's very exhausting. Any success stories for anyone in a similar situation as Chris and I? Please share I would be so appreciative.
