IUD removed while on last day of cycle

I had my IUD removed on day 5 of cycle. It was pretty much finished and the next day it picked up for another 5 days. I'm on day day 14 I've been takin LH tests since day 12 and they are negative . Could I have ovulated during the days I started bleeding again? Or do you think I just haven't ovulated yet? I stopped bleeding on day 10 but had light spotting on day 12, which is when I started testing. I'm so confused. Anyone ???
