a female question...serious answeres only? ok, if you go back and read my last question relating to my period and get the ndetails then you can probably answer this better. 
anyway, that was in march, didn't have a period since then. well,  i woke up this morning and had some dark brown spotting on my underwear and thought i was going to start. i was out of tampons so i put a pad on and went to work. 5 holurs later i went to the restroom and there was not a drop of anything . when i wiped there was a dark smear like dark blood. i have been home for 3 hours now and there is still no sign except dark when i wipe. and it's just a smudge. i have taken 2 peg test and they both came up neg(no surprise). do i count this as a period? do i talk to the doc now or wait a couple of days to see whast happens? what could be going on? i'm 22 so this ive been having periods since i was 11. please help. i don't have insurance and i'm wotried- should i be? ovarion cancer runs in the family and mom just got diagnosed with cervical cancer.
