Did I or did I not ovulate?

I just stopped my birth control last month, this is my first cycle unprotected... I have been charting my bbt and cm... I have thus far only had watery and sticky cm- BUT I saw a definite spike in my bbt indicating I had ovulated... So my question is... Did I ovulate? Is it possible without having any ewcm? I am supposed to start my period around the 16th.
