Sign of Ovulation

I recently lost 10 pounds (not much) but it helped regulate my cycle. My cycles were long and not consistent. After the small weight loss they have been consistent, 27-29 days for the past 3 months. This last cycle i even tested with ovulation strips and got a positive. Something that i was not getting in the past. And i had egg-white cervical mucus. I thought we were finally going to get a positive pregnancy test this month. But sadly we did not.

Is it the case that i am not ovulating? Even with all the signs there?
