Help!!! Share your experiences please

This is how my periods have been after getting off the pill (took my last pill June 9th got my period 2 days later):

5 day period - 32 day cycle

4 day period - 23 day cycle

6 day period - 33 day cycle

4 day period - 24 day cycle

5 day period - 29 day cycle

5 day period - 21 day cycle?

2 day period ?? I didn’t bleed for 2 full days it was more like 24 hours and it did not become heavier. And was the latest cycle not too short? I’ve had two short cycles before but I bled for 5-6 days afterwards.

Anyone recognize this? I’ve taken a pregnancy test but nothing shows. I’m really confused. Was that my period? If not then I am on cycle day 26. So maybe could get my period in a couple of days? Or could I have some sort of disease or something causing a bleed? Help guys!! Would love to hear about your experiences.
