27 going on 28 weeks

So at my doctor's appointment last Friday - I did not take the glucose challenge test because they booked my appointment for too late in the day, however it seems I have somehow managed to gain 12 pounds in 4 weeks as opposed to the usual 4 pounds that is average. Wow. The doctor wasn't too worried, my overall weight gain has been ok. The next day when I was home I weighed myself with clothes on and I weight 5 pounds less than I did at the doctor's office - so, go figure. I have an appointment this coming Tuesday to do the glucose challenge test & then in the afternoon I have another level 2 ultrasound at the hospital to check the baby's development. Hopefully she'll weigh about 2 pounds, and it will be nice to "see" her again. From this point forward I will be seeing my OB every 2 weeks. Work has been good, but now I need to start thinking about who is going to take over some of my responsibilities - paperwork is somewhat easy to hand off, however my managerial input is not something I can expect from really anyone else... so I'm still not sure what to do about that.
