Confused - help please 🤷🏻‍♀️

Staci 💕 • TTC for five months 👶🏻🙏🏻for a miracle 🙌🏼

So I thought I had missed my surge! But I’ve just taken another OPK and it’s gone darker than the others I’ve had over the last few days. I’m on CD 12 can anyone give me their opinions on what they think? Am I out for the month or? Still in the runnings?
