Help!

So at the beginning of the month after my period ended, my boyfriend and I tried not using a condom. He did like 2 thrusts but then we put a condom on. There was no Precum. I looked up if Precum had sperm in it, but scientists did a recent study hat showed there was either dead sperm or no sperm. Then later in the month we did the same exact thing. I take my combination birth control pill around the same time everyday, my period is supposed to start either tomorrow or moday, but I'm worried it won't come. Thursday I took a "tell you 6 days sooner" test. And it was one of the accurate ones. I don't know why I'm nervous bc the test came back negative. Is there any way that in could be pregnant?
