When and how long do I baby dance? It’s that time!

I got a peak solid smiley on my Clearblue Advanced Digital opk this morning. I also used a cheap strip with FMU (I know you’re not supposed to). I got the solid smiley so peak and is this a positive? I think so on the strip. but also aren’t you not supposed to use FMU? I guess I peaked last night so I have even less time? First time trying how long do I have to baby dance? Isn’t the Clearblue supposed to detect it slightly early? I’m not in the US so it’s the middle of the work day right now! Is it true bd today and for next three days because it can be a few days later when you ovulate? I don’t do temp testing. I’m terrified by tonight I’ll have missed it. Is there too much bd? Nervous!
