Hungry all the time

I am 10 weeks today. I don't get nauseous but my breasts are heavy and sore. Also feel bloated and I guess that might be the reason for the bump that I have. What I am worried about is that I am sleepy and hungry all the time. Even if I sleep for 8 to 9 hours I get sleepy again in some time and I am eating too much. Is anyone else going through this?
