Ways to ease my mind about pregnancy doubts

Hello fellow IM's,
I'm writing into you more for piece of mind.. I'm 9 weeks 5 days pregnant with pregnancy #5 but baby #2 I have had 1 live born and 3 MC's.. With this pregnancy I have had three bleeds and cramping, and I have a little red flag that keeps popping up to say not to get to attached.. And the worst may still happen. My last scan was at 8 weeks 5 days bub looked healthy and had a heartbeat of 167 bpm.. My anxiety towards pregnancy has gotten to me and I am even having dreams now that I go to my next scan (on Wednesday 15th ill be 10 weeks then and they don't find a heart beat :( I keep telling my self that it isn't real and its just a dream but its still making me freak out!!

Guess I'm just after tips to easy my mind
