Any fit moms out there?

So I have a couple of questions, this is baby #3 and prior to getting pregnant I was lean and fit- my caloric intake was probably suboptimal (I was really careful about what I ate)- likely less than 1100kcal per day. I also did weights and mod-heavy cardio (40% incline treadmill for 45 mins) 3 to 4 times a week.  I'm 6 weeks pregnant now and ravenous and am fatigued (which is expected) easily. My questions 1. How much weight did you gain in the first trimester , and then overall? 2. Did you keep the same excercise routine or cut back? Thanks!!
