pregnant???? HELP

I wanted to be extra safe so we used three condoms a few weeks ago I think one of them tore and another burst because he came so hard. My period is now two weeks late and I've been feeling ill in the mornings and my boyfriend said he's gonna break up with me because I've been so grumpy the whole time.  Could I be pregnant, I could taste some of the cum through the condom but my friend said you can only get pregnant through blow jobs if you swallow. Any help??
