I took Plan B 2/14 and got my cycle a week later; which is a week earlier thatn normal. I am not spotting dark brownish discharge for going a week and I am scared. I want to know if this is normal or should I go the ER? Also, if it is normal when will it stop? Please help me because I am really scared. Also, when I got my cycle I had severe cramps and heavy bleeding. AGAIN, PLEASE HELP ME!
