Ttc with no luck.

Well to start off I was pregnant at 18 and decided to have an abortion. I do regret it with all my heart.but ever since that I have not been able to get pregnant. Now I'm 26 and still ttc .don't want to go to a specialist cause I am afraid they will give me bad news. Family tell me I might not be with the right guy..ahhhh....getting really discouraged. .any advice? ?? Thank you!!
