my little sister is pregnant

my little sister just told me she is pregnant. I am so happy for her! my husband and I have been trying for over 4 years now to try and get pregnant, I am so happy God blessed her with another baby, she had a miscarriage about 2 years ago and it was very hard on her. I am happy, but I am also sad.. 4 years of trying and nothing.. but I am also very happy and I feel very blessed because my husband, who has been battling kidney failure for almost 4 years now has finally received a kidney transplant! we are hoping that with this kidney transplant that it will give us that chance to create our little baby. to grow our family ♡ I cannot help but to feel so much happiness and feel so blessed not only by our family growing from my baby sister but my husband getting a second chance at life ♡
