First appointment soon so nervous

I’ve been TTC for almost two years now and within that time I unfortunately had a miscarriage and also an ectopic pregnancy. Due to that a friend recommended me to her doctor and to start <a href="https://glowing.com/glow-fertility-program">IUI</a>. I really don’t know what to expect , my very first appointment is next Monday. Anyone have any advice or stories they can share to shed some hope.

Anyone get pregnant their first try ?

Can this increase chances of twins ?
