Infertility/abortion

Backstory:

Two almost three years ago, I was hooking up with a guy I met on bumble right after a 6 year relationship ended and got pregnant by him. Got back together with my ex right after, found out I was pregnant. I talked to both and we all agreed abortion because we were all too poor and irresponsible to care for a child. They found two sets of heart beats, hardest decision ever.

Fast forward to now:

I’m married, and we’ve been trying to conceive for the last year almost. Every single day since we started trying I’ve been overwhelmed with the thought of what could’ve/should’ve been and I’ve been feeling so guilty and disgusting. But now NOTHING IS HAPPENING. Do you think it’s because of my abortion and my negative feelings?
