infertility treatment

Ghadah
Hello everyone!
My husband and I are 28 and been trying to get pregnant for 3.5 years.
 Finally, we decided to see a doctor and I'm supposed to start my 1st cycle of clomid + hCG trigger shot + <a href="https://glowing.com/glow-fertility-program">IUI</a> in few days.
I'm just scared as it's my first time with medications and reading about all the side effects made me anxious about the hCG.
If anyone would like to share their story taking these medications, it would be very helpful.
Thanks!
