TTC after 2 miscarriages

Katie
So I've been trying to conceive for a little over a year and a half now. I managed to get pregnant in December of last year and lost the pregnancy at 5 wks. I then got pregnant again in April this year and lost the pregnancy at 6-8 wks. I'm super nervous that it's going to happen again! I don't even want to take a pregnancy test because even if it comes back positive I fear I'll get my hopes up again just to be heart broken again. Should I just wait for 2 missed periods before taking a test if I suspect pregnancy? I've been wanting another baby for 5 years now and it's not easy to not get my hopes up and start becoming attached when I see two pink lines. Will this fear ever subside?!
