Trying to stay hopeful...

My partner and I have been trying to concieve for over 2 years now, with two previous miscarriages. I have PCOS, but I've also struggled with drug addiction and eating disorders. I am still working on getting sober, but overall, I'm in OK health. I'm 18 years old, my parter and I have been together for almost 5 years and are very excited to start our tiny family, but we both feel like it's something that just isn't going to happen. I have very irregular periods, always have, but they seem to be smoothing out since I started taking my prenatals, so that have me some hope. I'm just so nervous and if we still aren't having and luck around October I'm going to see a fertility specialist. I don't know why I'm posting any of this... I suppose I just, felt like I needed to say something.
