Opk positive ? Need advice

This is my first time using an opk I Been #ttc#3 since March last year, I just turned 30 in October and I had an ectopic pregnancy last year that was not planned.... this is the first time I’ve seen my opk this dark so I just wanted some advice. I took it at about 10 this morning the one I took last night was not as dark but had 2 lines. I’m wondering am I ovulating now and how long do I have to baby dance before it’s too late ... Any advice is welcome and wish me luck baby dust to all 😘🙌🏽
