Why am I not getting pregnant!??

I have been ttc for 3 years! I have no existing issues, neither does my husband. We have done 3 rounds of

IUI

unsuccessfully. Been diagnosed and undetermined infertility. Starting to feel like I will never become a mother. I have no kids...I am so sad all of the time. What is going on!? I just want to be a mom so bad and my heat is aching. I hate this...

Update:

Thank you for all your kind words and recommendations in the comments. It’s been such a long and sad journey and I know I’m not alone but sometimes the breaking point seems more prominent than the journey itself. ❤️ So happy to have this support! thank you all!
