Hi seasoned TTC-ers... Just a quick question that I'm hoping you can help with. This is my first month using OPKs (the cheapie test strips).
OPK went very dark on Wednesday morning (CD13) and was still dark when I tested again on Wednesday evening, so we DTD Wednesday night and Thursday night (it's Friday morning where I am, just FYI!). We also DTD'd Monday evening.
Is this enough?! I don't think I can be bothered again tonight! 
Thanks all!
