gaining weight too fast

back story, I lost 100 pounds since I have birth 18 months ago. between a miscarriage and the holidays I got off track and gained about 10 back. now pregnant and I swear at 7 weeks 2 days I feel like I've gained another 10. I'm feeling really insecure about it. I do really great eating right through the day but I'm so nauseous when I'm hungry and by the evening I loose all willpower to stay away from junk. I just feel horrible about myself. I guess there's not really a question in there, I just don't have anybody to talk to and needed to vent. hubby is supportive in so many ways, but just doesn't get this and kind of makes me feel like I shouldn't even bring it up.
