Positive OPK

Samantha

Some of you may have saw my post last week about my sticks and I was so confused, but I THINK I finally got a positive opk this morning! Last night it was close and I had horrible cramping all morning. The only problem is I thought I ovulated already, so totally missed my window. My boyfriend is supposed to be home tonight, do you think I still have a chance? Maybe this isn't completely positive yet and I can still catch it?!
