Looking for some positive vibes

Hey all,
Gosh never knew pregnancy was going to be such a roller coaster.
I'm 6 weeks 4 days and early last week I had a couple of days of brown spotting with two small red bleeds lasting about 20 seconds each before returning to brown. It's stopped now. Had an ultrasound at 5 weeks 3 days and baby looked as it should but too early for a heartbeat. I'm going back in on Friday(6weeks 6 days) to see if it's grown. Super nervous and can't stop thinking about it. Trying to think positively but also being a little stoic. 
My sister in law had lots of bleeding in her pregnancy and she has a beautiful little girl. 
I still have lots of symptoms, pregnancy tests very strong/ 3+ weeks on clear blue. Never really had Ms, other than a bit quesy if I go without eating for a while. 
Would love some positive thoughts. I want this baby so much xx
