Hi...I took plan b on December 21st. My period was
Need a clarification...
You did not mention when were you involved in sexual intercourse. And after what time frame did you take plan B.
If plan B was used within 24 hours after the sexual exposure, then you are not likely to be pregnant. The current delay and mild spotting is the result of hormone change. Full period should resume in a day or two. And you need not be overly worried.
Hope this helps.
