Period or What??

I was almost 2 weeks early for my period (which is almost always on time to the day) but this month and last month it was early and random. No actual flow days just the weird beginning and then maybe one day of flow... If that. I’ve not needed any tampons the past two months.

What is this?? And yes I am trying to get pregnant and having unprotected sex throughout my cycles.

Should I test? Or what is going on? This is so confusing!
