I'm 22 years old and I have always has irregular periods. Irregular meaning that some time I get them twice a month. I am a heavy bleeder the first few days and I have bad cramps almost like sharp pain. Sometimes I'm always late or I start early before I'm supposed to. But my most recent problem my period is on and off. Something I would call spotting. My first two days were what's normal form me. But after the second day it seemed like I was done with my period but all the sudden in the afternoon I bleed for a little bit and it was gone. I has been like this for almost 4 days. Is this normal ? And no there is no possibility that I'm pregnant.
