I'm sick to my stomach

Today my doctor called and told me to come in for testing because I had 3 days of VERY light spotting before my period last month. I'm sick to my stomach because it's been almost 5 months since my miscarriage. I would be 7 months pregnant right now. Better yet my sister has just had another child.. I'm sick to my stomach because I'm all alone and can't get the feeling of never being able to have my own children out of my head. All I do is work and take care of my husband and step son. I've never felt so alone and not having my baby is so devastating. When will it be my turn?! When will I feel whole again?! I know I'm not the only person who's gone through loss but I am so exhausted. My whole like since the age of 10 has been loss after loss after loss. (I'm 23) I need a break and a sign of positivity!! Baby dust to all who are ttc. I pray you all have beautiful healthy pregnancies and for those who are waiting I pray you get your BFP soon! God Bless!
