Plan b

I took plan b in may and june.

Apparently it can stay in my system for 3 cycles, well this month was the 3rd month. And after my period i had experienced this sort of spotting which I don’t think I usually get. I started my period on the 4th September and this spotting came on the 11th.

Today i woke up feeling bloated and I didn’t have much energy, i also had abit of stomach pains too💀 Creamy white discharge

Has anyone taken plan b and experienced this on their 3rd cycle after taking it?

Is this related to my body regulating its cycle?
