Scared to hope

So I'm currently 13DPO, no sign of my period, I was pretty regular pre-miscarriage. Since the miscarriage, it seems like my cycle has been longer. It's never been this long though, but I'm really scared to test. Can't help wondering if I might be pregnant, but I am so scared that I'm getting my hopes up. I've tested in the past and had negatives that I thought would be positives, and it was absolutely devastating. Any advice? For whether I should test or if anyone has gone through the anxiety of waiting for your period and hoping you won't get it and being crushed when you either test or when it comes?
