Is this a positive?!

I'm charting everything because my obgyn wants to rush to the conclusion that I undoubtedly have PCOS, and I think she is incorrect on her assumption. So, I decided to see if my body was even ovulating when it should, and on top of temping, I started using opk's. I had a very sizable dip in temperature yesterday, and a spike today, and then got this (the last test on the list) for opk! I've never seen a positive in person, but this is darker than I've ever seen! Is this positive?! Please help ladies! Thanks so much!!
