being careful or careless????

So my husband and me just got married not to long ago.  He had already said he doesn't want kids for a couple more years. He also makes it very clear every time we have sex.. I would love one. Lately he has just been cumming in me.. and then saying hope you don't get pregnant. Like what?! Then it has become so regular now he's like your gonna get pregnant.." I just know it" I'm feeling mixed signals and I'm wondering if it's his way of saying he wants one ?
