could I be pregnant?

Teresa • I love to ride horses, four-wheeling, hiking, fishing. I'm engaged.
Is it a possibility? I've been craving different foods and feeling nauseous. I want pickles and vanilla ice cream with bacon on it. Also a pickle sandwich sounds good pickles with mayo and salt and pepper. Mmmmm yummy but seriously is it a possibility I've thrown up twice within the last 2-3 weeks.
