weird discharge after using plan b & after a week of ending period?

Ashley
This discharge came out??? I'm not on my period. I just ended it on Saturday. I have been having pain in my vagina, and cramps. I'm not on birth control, but after having unprotected sex (he did not ejaculate) I took plan b. This was about 2-3 weeks ago. Could this be because of plan b and the large dose of hormones my body Wild because Im not used to having that much in my system? Thank you.
