So I have been trying to get pregnant for last 2 yrs and now my doctor has suggested <a href="https://glowing.com/glow-fertility-program">IUI</a> - I finished my clomid session and have an appointment tomorrow to get my <a href="https://glowing.com/glow-fertility-program">IUI</a> scheduled...how effective is <a href="https://glowing.com/glow-fertility-program">IUI</a>? Can you get pregnant with the first treatment?
