OK.well my boyfriend put his thing in me a couple times with out of condom but ejactulation never happed inside of me or came close to happening then we did it twice with a condom and still ejactulation never happened or came close to happening but it was hard to tell if I was late or not because my period was very inconsistent from the time I was fourteen it would come one month maybe 2 weeks later have another then itd be a month or two before I had another one but then after we had sex my periods were very light and still inconsistent and one morning I woke up and puked twice. I have taken 2 pregnancy test about a month apart and they were both negative is it still possible that I'm pregnant?

Yes, it's always possible to be pregnant if you are female and had sex. We can't guess the probability.
