Hi, I’m new to bbt, this is my first month. Can anyone please help me make sense of my chart? I’m not sure when/if I ovulated as around the time I expected to, tests were all negative but I had ewcm. 🤷🏻‍♀️

(The <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> period and ovulation predictions are around a week later than my other apps which are normally spot on)

Any help would be much appreciated!
