Cataracts Treatment

Last night i fell asleep with my contacts on and this morning when i took them off to wear my glasses my left eye was irritated it was very red so i put some clear eye drops it was still bugging me a lot so i went to check my eye in the mirror and i looked closely and saw a small little white dot in my eye in the color part of my eye i thought it was like something that got in my eye so i tried removing it with my finger and it didn’t move then i realized its on my eye like a spot, I’m scared do i have cataracts? I have been wearing glasses since i was 13 im turning 17 this june, i’ve been wearing cotacts since i was 14 and a half, on july of 2007 i had my yearly eye exam and the doctor said i have astigmatism…..My uncle and both my grandmas have had cataract surgery, my dad has been wearing contacts and glasses for many many years now and hasn’t gotten cataracts so i dont know if it runs in the family or something…..please help!!!HELP!!! what do i do?
