OPK's question

Just a little confused. First time using OPKs. Saturday night, I experienced EWCM. I took an OPK and it was negative but much darker than it had been being so I knew Ovulation was just around the corner. Sunday night my husband and I Bd'd. Monday morning I recieved a dark positive OPK around 9:45am. We BD'd again when he got home that night around 10-11pm. I took ANOTHER OPK around 1am just because I have never had a positive and I just wanted to see it again. Sure enough, still just as positive maybe even a little darker than earlier. Tuesday morning around 10am I took another OPK and it was negative but similar to Saturday nights, still pretty close to being positive but not quite. We had sex again but this time couldn't until about 1am because of our work schedules being weird right now. Today (Wednesday) about 14 hours after we had sex I experienced EWCM again? I guess I'm confused because Glow says I'm out of my fertile window. O Was marked for Monday, with Tuesday being my last fertile day. I am experiencing slightly sore breasts, and cramping which I know is normally my ovulation symptoms. (WAY to early for it to be a pregnancy.) My question is could I have just now ovulated even though my OPKS returned to negative?

I hope BD'ing so late (with it technically falling under the next day since it is after midnight) doesn't interfere and knock my chances down this cycle. Really hoping this is my month.
