My bestfriend is pregnant, and I'm jealous..

My bestfriend just got married on 12th December 2015 and she announced her pregnancy today.. I felt happy and excited for her but.. I just couldn't help myself crying and feeling jealous..

I have TTC for a year now. And yes, no matter how hard i've tried to be positive, I couldn't help myself for not being jealous for any friends or family who got pregnant. I have tried talking about my feelings to my husband, and I do understand that he felt the same way too.

What should I do? I know my bestfriend would need my support since her husband, works a long distance from her, she has an ill single mother to be taken care off and she's the only child of the family. Yet, I couldn't hide my feeling over her joy. I kept it to myself and not letting her see myself cried.
