Unsure...

I and my husband have been getting along horribly for about 2 month's off and on and I wonder if it's because I'm pregnant. I'm unsure if we need to get pregnant even though we been actively trying 6 month's. I really have stopped caring or trying as of December but even more so this month but I could be pregnant because he's been getting nauseous spells and feeling like vomiting. And he did throw up the other morning. What's weird is our daughter has been super whiny and also when I mentioned something about the word baby he told me to stop saying that word because it made him feel more sick. He hasn't ever said that to me and we been prego 3 times before. But they was girls and the other baby I was 4 weeks pregnant and lost but I suspect was a girl too.
