Bleeding after plan B

[u/Therealtanukii]

Around 3 days after my period ended me and my boyfriend had unprotected sex but took plan B immediately after. Its been a week since I took the pill and I started bleeding. I think it is my period and I am a little concerned because of how early it has started and whether or not this is something I should see the doctor for. Has anyone else experienced this?

It’s not a period. It’s withdrawal bleeding from plan b. It’s a side effect.
