Impatiently waiting.

My husband and I have been trying for a baby for quite some time (about 5 months). We had taken a small break but started trying again. We had tried on 9/28 and we have been patiently waiting. I've been really nauseous, ive noticed breast changes, I can't stand  certain smells like bacon, onions and peanut butter. Could these be the signs we have been waiting for??
