Should I be scared of IVF?

I have an <a href="https://glowing.com/glow-fertility-program">ivf</a> consult this week I’m feeling really anxious and unsure about moving forward with <a href="https://glowing.com/glow-fertility-program">ivf</a> but am 40 years old and have been ttc #2 for 13 months post MC. 4 rounds of clomid, 2 rounds of femara 1 <a href="https://glowing.com/glow-fertility-program">IUI</a>. Why do I feel so scared? Should I be?
