Period/Ovulation overlap?

Hello, I'm TTC #1 and went off the pill a few months ago. After a couple months of no periods, I finally started a regular cycle on the first of this month. Almost 11 days later and I'm still seeing light spotting. It's very light, but still there.  My question is: can I be ovulating even if there is still spotting or will ovulation not start until it's completely over. I am starting to use an opk, but worry I'm wasting some.
