No faith

So I’ve had 3 miscarriages back to back and now I’m pregnant again.. all of my miscarriages have been around week 7-9. So this time I told my doctor I didn’t want an appointment until in the middle of week 9. I don’t want to get my hopes up for a heartbeat at week 6 just to not see it at week 7. I don’t know what to do at this point, I have no faith in this pregnancy at all. I just can’t bring myself to get excited to be let down again. I’m 6 weeks now btw.
