Ovulation after miscarriage

Hi everyone, I had a d and c 24th May due to a blighted ovum at 11 weeks. It is our first cycle trying again and I am sooo confused as to what is going on with my ovulation. My charts show ovulation being Saturday ish and then since then my opks have been getting darker! We haven’t been bd’ing since Sunday, do you think I tried to ovulate and didn’t and now it’s trying again? I just want this nightmare to be over and to have our rainbow baby. Next month I am going to have to try temping
