Is water weight normal?

[saranwrap21]

Ok I have the weirdest question for you pregnant women- well, first here is the situation- over a few weeks I was starting to gain weight (what I thought was fat) and everywhere on my body was growing- including my breasts to a full B where I almost needed a new bra (exciting for me because I am not even a full B when not pregnant).

But this past Monday I exercised like I normally do, light cardio and weights, and ever since then it's almost as if all of the "weight" I put on, is gone!  I mean, my stomach (i've always had a tummy, but it's not bloated like before) and my breasts have gone back to their normal pre-pregnancy size!  What gives?  Should I be concerned or is this water weight fluctuation completely normal?  I eat every hour, as healthy as possible and I don't do strenuous exercise.

I'm 8 weeks and 3 days along and don't have any other symptoms other than breast tenderness, tiredness, extremely moody, etc.  

????  can anyone relate?

thanks for the info- now that I think about it, I have heard of that, but this is my first and I am soooo nervous and scared. I freak out at the smallest variances, and when I lost my
"growing breasts" I was starting to get scared.. but I dont have any m/c symptoms, in fact, I have been feeling nauseous again.. something that went away two weeks ago!
I thought I was done with that..!!!  Being exhuasted went away too, but I seem to be having that again.. do symptoms come and go like this?  I know you said everyone is different, but gosh.

What causes it: It almost seems that your jeans start to feel snug as soon as the pregnancy test comes back positive — and you can thank the hormone progesterone for that puffy phenomenon. While progesterone is essential for maintaining a healthy pregnancy (it is, after all, the pro-gestation hormone), it also triggers that oh-so-delightful trio: bloating, burping, and farting. Why? Progesterone causes the smooth muscle tissue in your body (including the gastrointestinal tract) to relax. This slows down digestion, giving the nutrients from food you eat more time to enter your bloodstream and reach your baby. That's the good news. The bad news is this slower metabolism can cause bloating.
Everyone's body is different so one person might be like you and someone else might have it continuously.  If you are concerned, give your ob a call.
