When will it happen for us?

I’m tired of hearing my friends are pregnant. I’m tired of the announcements, the gender reveals, the baby showers and the pictures. I’m tired of feeling like I might be pregnant and then getting my period. My heart hurts. Why can’t we conceive? Why are we not able to do what others do so naturally? 5 years later, I approach my thirties and I feel like an old hag that’ll die alone. My SO says it’s not the end of the world and keeps hoping it’ll happen, but I feel like it won’t and he will end up leaving me eventually. Meanwhile, the world is falling apart. Maybe it’s for the best. But I’m tired.
