Anyone have any idea what is going on here?

Cass • Endo warrier, IVF 7/18 - ❌, IVF 9/18 - baby 🎀 and 4 ❄️, FET 8/20 👼🏻 & 10/27 👼🏻, FET 12/1 - baby 🦋, IVF 8/27 TBD
So this is my first month BBT charting and I'm very confused. A couple things to note are (1) I always temp at the same time, (2) I came down with a UTI on CD 7 and took antibiotics from CD 7-9 - could have caused some of the weird fluctuations around those days, and (3) I think glow has my period prediction wrong - it shouldn't ** be showing up in a day or two. Any help would be much appreciated. Thanks in advance!!
