I have sex three times and he used the pullout method my period came three days early the first night it was really heavy and dark brown didn't even look like blood the next day it was spotty and night brown my period has never lasted two days but it did.I took a pregnancy test yesterday and it said negative could it be to early? My breast have shocking pains sometimes and my back and back hurts and I puked a little bit last night could I be pregnant?

You are aware that the "pull out" method is the least reliable means of birth control, right?

Yes, it could be too early but I doubt you are pregnant this month, not if you had heavy bleeding.
