Nauseous when lying down

Trisha

My husband and I have been ttc for several months. For the past week, I've been getting really nauseous and sick in the morning right when I wake up and at night when I lay down. My period doesn't come till next week and I've tested a couple times and they're both negatives. I have to wait till next week for an accurate reading but I'm really nervous. Could I be pregnant?
