Ovulation testing - any advice


So I have a 2 year old but she came by accident so I was never worried about this! We are now trying for another and I’m taking the ovulation test! I? am new to this so kind or confused! When you get the go does that mean you want to do the baby dance right away for the next couple days ? Or even when the lines are as dark as they should you should still be doing it? My lines are getting darker so I know it’s coming soon. Wasn’t sure if you are supposed to be worried about sperm count and saving up until the day of! Any advice ?!
