I'm at 6w3d and I've already gained 5 lbs. I feel so tired but I can't sleep and I've been told not to take my regular medication which is totally understandable. I'm more irritable than ever and my 7 year old even tells me that I'm getting thicker. My first pregnancy I had no appetite and I was sick through the entire pregnancy. With this one, I'm actually having cravings and although I feel queasy most of the day, I'm still able to eat. I'm not eating too much, but more frequently, and I'm nervous that this is happening too soon. Am I the only one?
