Ovulation question!

Alexis

I had a blighted ovum 2 months ago and this is my first cycle trying since the miscarriage. I am so confused by what’s happening and it’s letting me down! I know I’m early in my cycle but why was the OPK test dark a few days ago and light now? It wasn’t positive, but was close. And I shouldn’t have ovulated so early in my cycle if it was positive? Will it get darker again or is this cycle pointless to even think about conceiving?
