confused, can you help?

First, thanks for reading- I hope someone can help! 
I had a chemical pregnancy over Christmas. Prior to this i had fairly regular cycles, 33-35 days with O on cd 21-23 and AF 10 days later. . I'm on cd23 and no LH surge yet. Is this normal? Should I expect a delay in O this month because of losing my baby? I've attached a picture of my OPKs (I do 2 a day in what should be my fertile week) and although there is a visible line there's no peak yet. I did do an HCG just incase but definitely BFN. I'm trying not to stress out but now I'm worried that I was only meant to get pregnant once :-(
