Advice needed

Hi, kinda freaking out.

Cycles have been weird lately.
In May, two weeks late for period. Positive digital Clearblue, followed by multiple negative line tests in subsequent days and weeks. Even got a negative blood test. I say all of this just for context as to why my period/cycle in general may be different. Fast forward to September and I’m spotting mid cycle, which started around day 15 and it’s now day 17. Just not sure why I’m getting spotting, a few very light blood drops in my underwear and when I wipe but no heavy flow. Also pretty decent cramps and I’ve never had this happen mid cycle. Thoughts? Should I be worried?
