Feel like giving up

My first two I conceived right away. Didn't even yet. Heck I was on bc with my second. Now trying for number three. Got off of my bc in may and have been trying ever since with no luck. One chemical in July. I get so heart broken when af comes. And it seems everyone around me is getting pregnant. It's like the universe is taunting me. And the majority of them didn't even try. One cousin is having a thud oops. I just really feel like giving up. I'm running or of time. I have to have treatment for something and it would cause scar tissue that I would have to have surgery again to enliven in hopes of having a chance.
