Weird OPKs?!

I feel like my OPKs this month are so weird! Usually they fade in for a couple days, turn positive, and then it's gone the next day. This month they taking forever. And I had one weird almost positive (or was it positive?) on day 11. What do you ladies think? Have I ovulated? Maybe I will be soon? Maybe I won't be at a this month? We are trying after having a chemical pregnancy last month.
