Friends find out the gender tomorrow and we are still ttc!

My husband and I have been ttc since August. We decided to keep it secret and only told a few of our friends. We will be starting Clomid in the next month or so because I recently found out that I am not ovulating. When we told his best friend and his wife that we were ttc, they were happy for us but neither wanted a baby of their own. After a few months went by, she texted me and told me that she had thrown away her birth control and they were going to officially try! After only one month of ttc, bam, they were pregnant! I was and I am very happy for them! Babies are miracles from God and I am so excited. Tomorrow, they find out the gender of the baby and I am having a really hard time with it. We recently went on a trip to the beach with the couple and I felt they were so inconsiderate of my husband and I and our feelings. I understand that they are excited, we all are, but I feel that they are bragging to an extent and do not respect that me and my husband have reached the 12 month mark with no success at all. They know the issues we are having but yet I feel they flaunt the fact they are having a child in front of our face. I asked her to only send me a message with boy or girl in it so I would know but she insisted that she was going to send us numerous photos that they are having done when they find out. Am I being selfish by not wanting to see the photos they are having done?
