I understand how you feel. I am in a similar situation, I have scaring on my felopian tubes. This has caused me to have three eptopic pregnancies, two of them in three month's time. I am 24 years old have been married for 3 years. My husband also has a child from a previous relationship. I can relate to your feelings about other peolpe having children that they don't want and won't take care of. But I believe that God has a plan for us, it may not be our time just yet. I hope that these words can be comforting to you. I welcome you to email me if you need to talk to someone that understands. You will be in my prayers. P.S. No physical problem in the world can prevent you from receiving your blessings.
