BBT Help!

This is my chart this month. I didn’t temp the whole month, since I know I probably won’t ovulate early. I just started charting last month though so I suppose I really should have temped every day, might have saved me the confusion. But anyways I woke up and temped on CD 19 after 3 days of EWCM and I had a spike. But then I had early shift and had to be up at 430am(usually I temp at 8am) and my temp was lower than 97.0. Then the next day I woke up early again(5am) and temped and my temp was 97.45. Today it was 97.7. But I had EWCM yesterday again. Which makes me think I might have not ovulated yet, that makes me nervous tho because it is CD 22 and my cycle is only 30 days. Last cycle I had a 9 day LP and was hoping it would be longer this month as I’ve been taking VIT C. Any help is appreciated.
