Weight gain in first trimester

Has anyone else had a higher weight gain than expected in the first trimester? I've gained about 7 pounds and I'm only at week 8. I have been so nauseous but the kicker is that if I don't eat something (it seems almost every 2 hours) my nausea get so much worse. I've started to make sure I have healthy snacks around to help with this to minimize bad options.  For the most part I'm still on my normal pre- pregnancy work outs - although this week I have fallen off a bit as I am just so tired I opted not to. Before pregnancy- I craved vegetables and salads. Now they are not rancid to me but definitely not calling my name right now. Just curious who else might be having a similar journey.
