Did I miss my ovulation time??

Okay. History: I've been on birth control for almost 3 years. I was taking the Lo Loestrin pill. This is my second cycle off the pill and our first month really TTC. While I was on the pill, my cycles were always regular-28 days. My first cycle off the pill was the same. Only difference was how horrible my period was (it was terrible before I started BC). I'm in my second cycle. Been tracking my bbt and CM and it's been pretty consistent for the last 7 days or so. CM has stayed watery - no sign of egg whites yet - and my cervical position has consistently been open, soft, and kinda high. Today it feels a lot higher than normal. Started taking ovulation tests Friday night (cd12) and they've been negative every day. Could I have missed it? Or could it still happen this late in my cycle if I'm regularly 28 days? Today is cd15. Or am I possibly not even ovulating? Haven't taken a test today because I haven't gone a full 4 hours without peeling and I don't want a negative because of watered down pee. Getting negative ovulation tests are almost as depressing as negative preggo tests because I don't even know if I'm ovulating at all. Any insights? Or advice? Maybe I'm stressing too much. It's just my first cycle I've really tracked and I feel like I have no clue what my body is doing! Thanks for responding!
