Worried and anxious!

Liz
Hi ladies,
​I'm 9 weeks 2 days pregnant after having an early miscarriage before. 
​I've been in for an early ultrasound and got to see my little dot and hear the heartbeat at 6 weeks 2 days (I had thought I was 7+4 according to LMP!). Was told everything was looking good, and to go back at 12wks for next u/s.
​I was having some nausea (but not loads) pretty much every day, feeling really exhausted, and boobs were killing me! My skin has started to break out too.
​Over the last few days, I'm still tired and spotty (attractive!) but my other symptoms are fading, if not leaving completely! I know I should be pleased, but I've heard lots of women say they feel cramping with they're uterus stretching. I haven't really had that. I've also read about babies who just stop growing and the parents find out weeks later that they died. I'm freaking myself out! I don't really 'feel' pregnant. Do I need to go see my obgyn, do you think? Or worrying about nothing and should be grateful I don't feel worse?! 
​Thank you!
