Nightmares!!

A
So in the past five years will my so we've experienced 3 miscarriages. I'm almost 10wks(tomorrow) and this week I don't feel pregnant at all. Other than being sick all night still just nauseous no vomiting, gas, and the occasional breast tenderness. This past week I've been having nightmares sometimes several in a night. I had one where my dad got hurt and died, but most are about the baby and losing the one we have. This is the only week we haven't had a dr appt and seen baby on the ultrasound so I don't if that's why. The first week baby's heartbeat was 73 the following week it was 128 and last week it was 170. I'm just so worked up that things are going wrong. I think it's the dreams but I cried myself to sleep last night it's that upsetting.
