Did your fertility dr prescribe you with letrozole or clomid? I tried for 4 years and finally conceived on letrozole. I did IUI once, it was successful but ended in miscarriage. If you’re not into invasive treatment yet (IUI/IVF), you can ask your fertility dr about letrozole or clomid. Usually they’ll let you try for a few cycles first before going into IUI or IVF.
