Positive OPK?

My periods have been kind of wacky since the baby...like I'm on cycle day 50 something right now. Baby was born April 23rd so I'm almost 4 months post partum. In this picture are two OPKs that I took a week or so ago and the top one is the one I took today. My question is does the one from today look positive? I know it's supposed to be close to the control strip but when I was using these last year to plan our pregnancy I never got a stripe as dark as the control and got pregnant. We are avoiding pregnancy right now but we fooled around last night and this morning! I tested because I had been extremely frisky. But, I assumed since I haven't had a period in two months that my ovulation just wasn't happening. What do you guys think???

PS- I've also taken 2 pregnancy tests in the last couple of weeks and they were both negative.
