HELP HELP HELP

Help ladies! this is my first pregnancy after so much trying and I’m crying my eyes out. Boyfriend doesn’t understand. Thing is, just TODAY I read for the very first time about missed / silent miscarriage. I am freaking out that I can still “feel” pregnant yet get to the first ultrasound (mine is on 19.12) and find no heartbeat. How am I gonna make it till then?

Today is the beginning of my 5th week and although I do have mild cramping, today I woke up really energetic and my boobs are not that sore as they were last week. Is this normal?

Help please my thoughts are driving me crazy !
