Starving!

Omg. .. is anyone else feel a sudden increase in appetite? I'm only 7 weeks pregnant and I am considered overweight. 5'5" 198lbs. I gained like 10 lbs in the fiat 4 weeks. I had no idea I was pregnant and I thought I was just bloated! Then found out I was pregnant. I still eat the same amount of calories I was before. I eat breakfast ands then a snack of a 1/2 of mixed almonds about 2 hours later. Lunch and then another snack then dinner. Even though I make sure I eat fulfilling meals with protein to help curb the hunger but 2 hours after I eat and even after a snack I'm so hungry! My stomach starts to hurt growl with hunger pains and I feel of I don't eat something I will faint from being famished! (Farfetched I know but still! ) I also wake up super hungry as well. Doesn't help I have morning sickness so I find it hard to eat in the morning but I do it anyways.

Anyone else experiencing this? BTW this is my second ands my first was not like this. I'm also showing already at 8 weeks. Lol going to be a long 40 weeks!
