Ok so i had my normal period that i get monthly on 7/23. Eighteen days later on 8/10 i started spotting brownish blood. The next day it was heavy with cramps like a normal period? Me and my boyfriend were sexually active between the periods above and after, i dont know if that has anything to do with it, but now im not having my normal expected period which was suppose to be two days ago, 8/22. Today i have a sticky, whitish, discharge, no odor, 8/24. Any ideas what could be going on with me???

P.S my periods are like clock work. They come the same day every month. Except this month :-(
