2 Months Late Period

Princess
So I usually log my periods on here and the last day I got my period was Aug. 3.. so it's been 2 months ! I'm not pregnant and also when I fingered my self I bled  ? But that was a month ago . I've started college and I've been really stressed my eating patterns are strange , and just my whole routine. But before all that when I graduated HS my periods been very inconsistent lately.. someone help ? Idk what's going on I haven't been sexually active since NOVEMBER. So it's impossible for me to be pregnant.
