Cycles getting longer each month after BC..why??

Yael

Hi so I stopped bc 5 months ago and since have had 29,30,31, and 34 day cycles. I’m now on day 38, 4 days late from expected period, negative pregnancy tests. Anyone experience something similar? I don’t understand why my cycle gets longer each month and it’s a little concerning to me. Also I felt some cramps on Sunday and Monday as if my period was already here but not even a drop...
