My period is three weeks late, and the cycle has been irregular already in the sense of the timing of the month it comes. Me and my Boyfriend fooled around the weekend before I was supposed to start my period. But there was no penetration, just "bump and grind" I guess you could say. I have gotten symptoms of being on my period, like bloating and swollen and tender breasts, but I only had withdraw. This morning I had felt like I started because when I went to the restroom I had brownish red withdraw, the kind you get when you start your period. But throughout the day it feels like it is starting to cease. An added note, right now I feel a kind of tenderness "down there", like slight cramps. What am I to think of all this?
