PMS Premenstrual Syndrome Forums: I am 15 years old. I just moved in with my aunt and I am not comfortable with asking her questions. I've had my period since I was 13 and each time I had it- it was like tissue and blood. I got my period in the beginning of August. Now it's August 24 and I have it again--this is the first day. So far there is no tissue it's just blood. Is that normal? I have cramps like usual. Is this normal or am I just being paranoid? What do you think?
