1st time with OPK: help!

Jenna • Married 10-17-2015. Boy Mom. Dog Mom.

I just started using the opk. I am going on 10 days late for AF, no signs. I was frustrated since this is the first month of us trying, and no AF. Well I started the opk and this was my test from this morning.

Yesterdays opk was negative but we still has sex last night.

What are your thoughts? What do I do now? It it truly BD’in time? I need some advice from you ladies who have used these.
