What am i doing wrong ?

It hurts when you been trying for a baby and nothing. People say "just keep trying" but its hard especially when everyone else around you gets pregnant right away, dont get me wrong im happy for others! Just being able to be called mommy would be such a blessing, theres times where i dont want to even have sex anymore and theres times i blame myself then other times my boyfriend because he smokes (weed) all the time. Ugh, but

Life goes on ..
