Late night thoughts (sorry kind of long)

I’ve been sitting here seeing all my friends and family having babies and getting pregnant and it just upsets me so much. When will it be my turn? I lost my son when I was 8 and a half months pregnant, then had a Miscarriage in November 2018, and I just get so upset thinking about how lucky everyone is. I’ve been having a little bit of my pregnancy symptoms but all negative tests. Am I testing to early? AF is suppose to come the 27th and there hasn’t even been a faint line? Any thoughts? Don’t want to get my hopes up again.
