Feeling happy and feeling sad

Today I feel happy and I feel sad. I had a friend of mine have her baby girl who is so precious and I'm so happy for her and her husband and her son then also today I have a friend who miscarried who has been trying to get pregnant with baby number 2 for longer then I have. These are both amazing woman and both amazing moms. I too struggle with getting pregnant. I have my days where I am down and upset and I think why can't I get pregnant again..did I do something wrong? But for each once of my freiends who have babies no matter how much there is a little jealousy in me I am so happy for them! All my friends are great moms or going to be great moms and for my friend who lost her baby I feel so sad for and am so sorry! I know that God will bless her again.
