Everyone is pregnant and it's breaking my heart

Everyone I know is pregnant around me! Literally everyone. Or if there not pregnant, they have already had their sweet babies. That's all I see on Facebook, Instagram, Twitter....it's getting harder for me day by day to see positive pregnancy tests, congratulation comments, hospital pics of sweet babies, friends holding there child, ultra sounds, insanely cute baby pics, baby bumps...I don't think I can take it anymore. I'm so happy for all of them, God it's such a blessing, I'm so excited for the wonderful blessing in there lives....but when will I get to post a positive pregnancy test & reveal my big news? When will I hold a ultra sound or listen to my little ones heart beat? Or feel little kicks from him or her? When will I hold my entire world in my arms? My husband & I have been ttc for 7 months now, I just feel like I'm failing. My heart breaks each month I get my period. The look on my husbands face each month I tell him I started or the silence & huff when I ask him to pick up some tampons on the way home....I just want to be a mother. I feel like a failure. I know I know maybe it's not my time or it will happen when it happens but I get so frustrated...so many women abort their babies, & I'm praying hoping I get a chance to get pregnant & give mine a life. It's just not fair. Can anyone relate? Any sucess stories to literally give me hope? I feel like I will never conceive & it's breaking my heart.
