Discouraged

Mary
I love reading the forums and viewing the support you all give one another. 
​I'm 34 and had my one and only child when I was 28. I had no trouble concieving. We weren't even trying. I was pregnant within three months of meeting my now husband. 
​We didn't want another until about a year ago. After trying now for a year, nothing. I have been to the doctor and there appears to be nothing wrong with me that would prevent me from getting pregnant. 
​I'm frustrated and sad and just needed to get it out.  
​It doesn't help that my sister in law is on her fourth.   I feel like a failure.
