no lh surge. could I still be pregnant?

Katie
So I had an hsg test done on the 10th of this month, which was cycle day 7. I normally ovulate on CD 9-12. I never got an actually positive opk test. My af is due this weekend or early next week. I'm hoping to hear ladies who have had the same experience, no lh surge but positive pregnancy test. Anyone deal with this before? Here are my test.. tests are from  CD 9 &10
