my first three pregnancies were hellish in that i threw up enough to lose 30 lbs each time, but that hasn't happened with #4 (i'm 38 weeks too). however, this pregnancy i've been sick the entire time... throwing up 2 or 3 times a week all the way through. the nausea pretty much quit with the others by about 20 weeks, so this has been an unpleasant surprise, to say the least!
it hasn't been significantly worse for me towards the end, but i can say that my experience has led me to believe that pregnancy in general just wreaks havoc with your digestive system, and it's not predictable just how either.
all i can say, mama, is that we're in the home stretch!
(oh, and spaghetti sauce would do me in right now... onions, tomatoes, garlic... yikes! even a little cilantro makes my heartburn flare up...)
