Help with BBT please!

Can anyone help me with my chart? According to glow O date was 1/1/19. Another app says 12/29/18. I know these are only predictions so I’m trying to figure out if I’ve actually ovulated yet. I did have EWCM in the 27th and 29th (shown in chart) and some cramping on the 31st. . I had a UTI just after my period and was on antibiotics for 3 days. Not sure if this is helpful info as well.

*I ususally temp anywhere from 5-8am due to varying work schedule. Any ideas? Should I just disregard since I haven’t taken at the same time every morning?

Thank you in advance!
