Already Done - and it hasn't begun!

Anyone else as over being pregnant as I am? I know this is supposed to be a happy time, but I just want the baby here already! This is my third pregnancy - and no babies. With my history of miscarriage, I'm having a hard time enjoying these early stages of pregnancy. My ultrasound at '5w5d' should've put me at ease, but the combination of no heartbeat and now the insane cramps, I'm feeling really discouraged. 😔 Last night I had a dream I miscarried, and woke up in an INSANE amount Of pain - but there wasn't any blood, and they eventually went away enough for me to sleep. All day today I've been having bad cramps on my left side, and I'm beyond scared. I'm ready for this baby. I can't handle the heartbreak again.
