Have you experienced ? Or know?

I just ended my period last month on (3/30/22)and I randomly started bleeding yesterday (4/14/22)….This never happens…yes i usually do spot especially when im ovulating but this time is different im bleeding as if i was on my period! However, when i get my period i know days before by my mood swings,sore breast,cramps…this time no signs!

My symptoms are: major cramps back and front,bleeding,headache ,super tired

Could this be results on taking plan B 7 days ago? Or no

Can someone tell me if you had this happen before or know what it could be???
