Can anyone help? Thanks

I have been travelling since CD14. The dots you see until CD 17 are due to the many flights I had to take back to back. The country I arrived to was warmer, so I assumed that this is the reason why the temp got slightly warmer. Then I got several positive OPKs on CD19, but my temp didn't do a good jump until CD 22, although it rose slightly on CD 21. On CD 23 I had to travel to another city by short flight, same on CD 24. I have been on the same place during this last week, and I was sick on CD 26. Other than that I don't know why I have so many zig zags. When do you think I will get my period? Have you ever seen anything like this? Thanks!
