I need help. This is the first time I've ever tooken plan b. Which I've always been skeptical of. But I was concerned the morning after so I took it. My period ended the 18th. I took the pill on the 22nd. And today the 28th. I felt a little amount of brownish blood come out of me this morning. Then when I next went to the restroom there was more blood. I'm just concerned my period just ended and I don't know if I'm supposed to bleed a certain amount or if I'm supposed to get my period early but this is REALLY earlier. 3 weeks early. Help I'm concerned.
