Any idea?

Any idea when I ovulated? I’m so confused. My January period came early and was shorter than normal. I didn’t really get a positive ovulation test so the app just kept pushing my ovulation date back. My strongest reading was Jan 16th which was making my period due on Jan 30. (See pics). I took a PT this morning and didn’t see anything but I’ve been feeling like my uterus feels bulky like when I was pregnant with my first. Any ideas appreciated!
