things to do to distract you from worrying about baby

Alex • Blessed to be mom to our miracle IUGR baby boy! I've never met someone as strong and brave as he is!
I'm 4 weeks. I'm excited and happy but also terrified of losing this baby. My family has a history of miscarriage and 4 weeks means of course more likely to happen now than 8 weeks. That, combined with not really knowing how baby is doing is scaring me. What do you do to keep your mind off of it?
So far I've told myself to enjoy it, that there isn't anything I can control about it anyway, to just take care of myself. 
And also that I'd be bleeding if I were miscarrying. Still hasn't stopped me from POAS and obsessing about if the lines are darker than before or not.
