Trouble ttc venting......

Struggling with getting pregnant is so hard. It's exhausting. My SO and I want a child so badly. There are so many people, everywhere, who don't even like or want their own children. People getting pregnant who are not even trying and getting upset about it. I truely believe God has a plan and that a child like it says in the bible is a reward from God. I'm a devoted Christian who tries my very best to live right and be a good person. But I've still haven't had a bfp in 2.5 years! I'm loosing hope. I can't afford <a href="https://glowing.com/glow-fertility-program">ivf</a> or tons of fertility drugs or adoption. I've done all the testing I can do. I just don't understand why God blesses people with children they don't appreciate or abuse. But he won't bless me. It's eating at my soul. My SO and I want a large family but I'm so scared our dreams are starting to shatter. I can't seem to get a bfp to save my life. I'm disappointed in myself. He starting to get concerned and is frustrated. He is understanding and sensitive but i feel so guilty. Anybody with me? Any words of advice?
