Why??

Ive been trying for 7months, but only 5 cylces due to extended cycles length. I know it sounds selfish, but I cant help but think 'why me?' I have so many friends and family members getting pregnant and it is so frustrating bc I know that I have better means of supporting them..and some of them are on number 4 or 5! Its just frustrating. I cant help but begin to think its NEVER going to happen.
