I had sex on November 25 and I took plan B within an hour of it happening. I had just ended my period the day before. A week after taking plan B (this was December 3) I started bleeding for about 3 days. I know this was probably the pill causing it and from what I understand it's not my period. And I had just ended my period about a week before that. It's now December 24 and I still have not had my period so I'm confused as to if I'm still going to have my period this month sense I was bleeding for 3 days already this month or if it's possible it could just be late? Hopefully I'm not pregnant
