Strange signs

So I am so interested to know...we all know that the usual symptom of pregnancy are sore breast, missed period, cramping, nausea etc. But what about those weird symptoms. My mom was telling me how she would get up in the morning and feel a cold coming on during the first part of her 1st trimester. She also couldn't eat anything but beef with me and chicken with my brother or she'd throw up. What were your weird symptoms? Did you know you were pregnant yet?
