Why Doesn't My Mom Understand MY PMS?????!!!!!

Hi, Sometimes I feel like my mom is really a man in a woman's body, because she doesn't seem to understand my PMS!!!!!  I get REALLY irritated when I'm PMSing!!!!  Sometimes to the point where I just want to tell people to, "Shut the f*** up!"  Even the most legit things such as requests, reminders, corrections, or suggestions can REALLY send me over the edge!!!!!!!  If I tell my mom that I'm PMSing, she sometimes says something like, "Well, stop it!"  I cry more easily too (I usually don't cry very easily), but I don't think that's as bad as the short temper.  I have Asperger Syndrome (mild form of Autism in which speech and cognitive abilities are within normal limits), and that makes it harder for me to think about other peoples' feelings (though, I do try).  But this gets worse right before my period when my hormones are all over the place.  Usually I'm a very sweet young lady, but during the 1-2 weeks before my period, I get EXTREMELY moody and short tempered!!!!!!  I have even said things I didn't mean because of PMS!!!!!  Once I'm on my period, though, my hormones shift and I go back to being my normal friendly self.  My mom has suggested that I ask about birth control pills, so I can be more myself at all times, but I've heard birth control stops your periods.  My period itself isn't that bad, it's just the PMS that's a prob.
