Ok ladies, so I'm new to this whole ttc thing. I just took an OPK and I think it's positive?!? The two lines look the same to me, but I could be seeing things. What do you think? For a comparison, I included other tests I took earlier in the week. The first is from two days ago, the second is from yesterday, and the bottom two are from today.

If it is positive, how long is my ovulation window? Hubby is out of town til tomorrow night. Is that too late to baby dance? I need some advice.
