early period?

Shelly
so yesterday was the first day of school and i dressed nice ( white pants and a light blue blouse) and i didn't start my "period" until i was at school so i had nothing i needed, but my boyfriend did so he gave me a couple and i just used a pad instead, but when i got home it had almost no blood At all, and this is day 2 and im still not bleeding >.<
(2 days ago i had protected sex and he didnt cum) i dont think I'm pregnant cause last month was 2 months late, but this time 3 weeks early and this too?
im so confused please help
