Frustrated

This is really my first time coming to the community pages. I have no where else to vent. Im pretty frustrated with all of this fertility stuff. I have PCOS. I've had 2 miscarriages and I've been married for 6 years. I've gone through different rounds of chlomid and have recently upped my metformin. My insurance, like so many, does not cover fertility. I can honestly say that I feel heartbroken at the thought of the possibility of not having children. I have a great husband and we are happily married, we have a great relationship, we've known each other since we were 12 and we are 32 now. 
I've been spotting for 25 days now, 25! I just had my gallbladder removed so I missed a lot of work and I can't really miss anymore. I don't know why it's happening or why it won't stop. 
I guess I'm frustrated because I feel like we are ready and we've done everything in the order it should be: got married, then moved in together, finished school, bought a house, volunteer in our community, etc. Yet, everyone around us who was mean, careless, selfish, etc. is getting everything they want and some of them aren't even raising their own kids. I'm just waiting for it to be our turn and I get a little discouraged sometimes. 
I have a lot of faith and I know that God will give us the desires of our hearts. I guess the waiting is the hard part. My friends all have kids or don't want them yet. Is there anyone out there who can relate?
