Questions?

Werdah

This is my first IUI so I'm very new to all this. After reading many posts I have some questions. Should I take oral meds or injectables? I ovulate on my own just low semen from my husband's side. Should I proceed with the IUI with 1 egg or only if there are more? Should I take C10 (idk what it's called?) And make my husband take zinc? We are both on multivitamins. What else can I do to increase my chances of success?
