Anyone else frustrated at the process and seeming selective pregnancy from the universe?

Just got news, before anyone aside from her husband knows, that a close family member is pregnant while using BC and condom. I should add she has PCOS and half a thyroid (small bit of cancer removed a couple months ago). I’ve been trying for 7 years with no protection, PCOS, tried meds 3 separate times, <a href="https://glowing.com/glow-fertility-program">IUI</a>, etc and still nothing. We have one child that we spent thousands to get pregnant with 7 years ago and I know I should just only focus on being happy and content with that child but I desperately want more. It’s depressing sometimes. My husband is so involved and loving and deserves a million more kids but I’m a failure. I can’t help but feel like a total and complete failure.

Why are some people so lucky?! Why does it have to be like this? Why do we have to struggle and spend so much money and still have no results?!
